when your chemistry teacher can't teach... crashcourse saves you

[@aayushniraula84]

sahi ho

[@akshatapatwardhan4162]

true

[@janpatricetalucod4147]

yes^

[@shine-zj2bz]

Speed Demo that's so true 😂

[@florrrina]

LITERALLY SO TRUE And sadly Chemistry is a subject that you absolutely NEED a good teacher for, someone who knows what they are doing

[@Tomozaurus]

This has got to be the most helpful channel on KZbin.

[@hannahcarmelarojo6013]

Tom Parker AMEN!!!!

[@JohnWayne2122]

This 11 minute video taught me more than 6 hours of lecture... No wonder our education system is circling the drain

[@mayanklongiany6311]

JohnWayne2122 which country are you from? I'm from India and India's education system is trash

[@Syeal7]

Please don't break their dreams. Also, don't tell them the production cost and all the people behind the scene who made even one episode possible. And how that in no shape or form can compare to the resources that are put in a school classroom. Except if the student/pupil hasn't paid a fortune to go in a private top tier school with the best teachers and resources available for their privileged education.

[@Stoneface_]

@John Smith exactly

[@Stoneface_]

@John Smith i downloaded it but i can't do a single question. Am in high school though.

[@215serrano]

I agree . so much time and this video hits everything

[@MR-sd2of]

God bless "Crash Course". The reason I pass my science tests.

[@SebastianCarewe]

Who?

[@tapper666]

@ammar siddiqui But this channel is CrashCourse, I don't see any Crash Course here.

[@ezogo]

Hey Hank, whenever you have a minute, PLEASE CORRECT THE ERROR at 10:12. Dehydrogenation is NOT the removal of a water molecule. Rather, it is the removal of hydrogen. Thank you for yet another awesome video!

[@tjentertainmentstudio]

I wanted to say that as well. Good thing that someone else also noticed that!

[@leijolie]

Same I thought I was the only one lol

[@adamkolb9136]

Park City me too!!! LOL. :)

[@jembo9311]

he didn't say that, said it was the removal of hydrogen 10:09

[@jembo9311]

I believe that was an editing error on thought cafe's part

[@nancycharlton534]

i left this playlist playing and listened to it all night. i woke up at 5 in the morning thinking of hydrocarbons before i realised u were speaking to me through the speakers. weird night.

[@privateconfessions7821]

nancy charlton where does he talk about the reactions

[@MrDoubleT123]

My teachers sure could learn from this

Organic Chem quiz tomorrow... This is helping so far

[@heart0fthedrag0n]

Finally! Got to the topics that I'll study in chemistry this year. Even though it's in English(which is not my native language), I finally understood what our chemistry teacher was talking about in the past 2 months. Keep up the awesome vids, guys!

[@Hutts]

I'm so happy I didn't take organic chemistry in college :)

[@AlooshSABBAH]

1 year later

[@chemxcore]

Yes! Very excited to see your series on organic chem, this episode was great! As a chemistry major myself, I always enjoyed organic chemistry, even up through the crazy advanced and drug synthesis classes, and it will be good to have a refresher of the basics lol. Your videos are excellent, don't stop making them!

[@modolief]

Hank Green is a KZbin rock star.

[@randomtrucks]

I hate chemistry. I'm serious, there is no other subject in school that I hate more (exept physics, maybe). To my defense: I blame my teachers. But anyway, I have a chemistry exam in two days which I NEED TO PASS, or else I'm fucked. I think the only way to do it is to binge watch the chemistry crash course videos - which is fine since they're incredibly comfortable to watch and even actually interesting. I love the way Hank explains everything as if it's not part of a huge complex random fucked-up system that I'll never get to understand. It's way easier than I thought. Thank you so so so much, Hank (and crash course team) for doing this. You're literally saving me. So let me rephrase my first sentence: I hate the way they taught me chemistry, but I love the way crash course teaches it.

[@NorthProductions]

You stink then. I love science... I'm passionate for it! And I'm only 11.

[@jsherer9616]

aidenx lego That explains why you still love it. Wait until you're in sophomore year.

[@jsherer9616]

And, by the way, he's not literally saving you unless you will die without his help.

[@SreehariRajendran48]

Teachers....I know what you mean...

[@InfinityBeard]

John Sherer I loved science at 11, and I still love it at 24. I'm currently studying neuroscience in college and have been for the last 3 years. Who knows, he may get older and decide to go into more serious scientific study.

[@kendo9668]

I watched this entire series last year for my csec exams and now I'm watching them again for pre-med. Crash course is awesome and now they even have physics!! Can it get any better?

[@mohammedtaha2128]

The way he says Organic Chemistry summarizes how everyone feels about Organic Chemistry :D

[@bethysboutique]

Poor Organic Chemistry. It just wants to be loved.

[@wasserruebenvergilbungsvirus]

it's the most interesting kind of chemistry though

[@kerokerobonita]

I'm struggling so much with this at school 😑😑😑 but now I kinda get it 😊 a good teacher really makes a difference

[@wompstopm123]

HOW IS IT THAT I JUST FOUND THIS CHANNEL? hank green is 2000 times better at teaching science than my dorky ass teachers!

[@epaxinc1019]

Which class are you?

[@wompstopm123]

chemistry, thats why im watching this video

[@epaxinc1019]

yes, but I mean high school right? which grade*

[@Derpsii]

+epaxinc I'm in 5th grade so.......

[@liloo5146]

yours teachers got to punish you

[@chantalpiat]

These chemistry videos are almost completely in sync to every unit I'm taking in chem this year which is so freaking convenient. Thank you Hank!

[@emily.g.929]

my O-chem/biochem professor is really terrible at explaining things, and it doesnt help that she is european so her accent combined with choppy sentence structures and grammar make the class impossible. thank the heavens i found this channel, im going to pass the class now!

[@tonianic1537]

Thank you Hank My name is Toni and I'm 14 I am preparing for a Chemestry competition in my country(Croatia),and I just couldn't realize how to name alkanes But now,thanks to you,I get it Thank you Crash Course Chemestry!:)

[@kwamecharles6037]

@Ignited TNT hahaha

[@FiresideCat]

I'm nearing the end of my first semester of Ochem and I really fell in love with it. I wish we had gotten to organic chem earlier in Crash Course as my final is in a few weeks. Oh well, still very happy to be able to review with Hank!

[@LagMar100]

I just realized the reason so many of us learn much more from Hank and many other youtube videos. Our teachers eventhough we bash them, they try, but the manner in witch Hank explains, its like I had to hear it again but in different words and in a different order. So, language here is critical for one to understand the information.

[@kirs29ty]

Hank and John are obviously both intellectually gifted which is kind of logical since the intellectual quotient is actually a matter of genes, and yes Hank, you speak way wayy wayy too fast for my questions to settle up, but I love you because that is a more proper way to learn than that offered at school. Sincerely, I never actually follow any class at school, always daydreaming ( about people, and ants, and books, and atoms) and getting to study on my own is way easier with those videos.

[@bethysboutique]

I wonder how many med students have watched this.

[@krissyviernes8385]

Too many.

[@bethysboutique]

+Gaile Viernes including me. Well, pre-med.

[@tambourineman6653]

+Bethany Marty I'm watching this of my own volition to further my understanding of the world instead of trying to memorize information to pass a test.

I consider this studying chemistry. Never again will I have to bring home my heavy chemistry book to study.

[@hellohuman7903]

I’m in 8th grade about to get in College and Career Readiness, all my life ever since I was in 1st grade I wanted to take after my mom and be a Chemical Engineer. Now years later I finally realize that I’m just forcing myself to do I job that I don’t want to because of my parents. Don’t get me wrong I love Chemistry with all my heart, but I just couldn’t see me in that position. Since then I also knew that I was going to go to high school next year, with makes me conclude to me needing to make an image of what I’m going to do with my life. I am doing Biology right now so I’m going to do Chemistry next year. My mom introduced me to Chemistry when I was in the 6th grade, to show me a bit of what she does. I’ve been hunting a few ideas for jobs and I think Organic Chemistry might be the one. Even though I don’t know a lot about this subject, I can image myself in college studying hard to be a Chemist. Thank you for making this video. :)

[@ThatNerdyFreak]

This is going to be so helpful for my organic chem course in this upcoming semester. Thanks Hank!

[@SophieStillHasLegs]

This is precisely the chemistry lesson I had today. Was nice to be able to go over it by watching KZbin instead of just reading notes :3

[@danieldempsey3463]

L

[@linguaphilly]

Ok seriously everybody is exaggerating so much about his talking speed! Just pause the video if you need a moment to reflect on what he implies! If not, you can just sit back and enjoy without losing your attention because the teacher is dwelling eternally on one thing (I hate when teachers do that)

[@gaudiumrome]

linguaphile Yeah I paused a few times and rewinded

[@noncreativefakename6381]

Exactly. Who wants to click on an hour long video? It's discouraging.

[@TechLaboratories]

It's like the best refresher of High School chemistry nomenclature that I've had in a while.. and actually needed..

[@loupagoo]

"properly proper chemists"

OMG WHY DID I DISCOVER THIS NOW I HAVE A TEST ABOUT THIS TOMORROW!

[@dominicwynter4805]

Finally! Organic chemistry. I've been looking forward to this for a while.

[@brontecross1062]

Just so you know, your the reason i love chemistry. Without you i don't know where i'd be. Thankyou form the bottom of my heart

[@saud9333]

Go to 8:50 and change the speed to 0.5....

[@AllNewYork11]

Hi! I am biomedical engineering major and I took Organic Chemistry 1 and 2 about two years ago. These videos are so helpful for reviewing forgotten material that I'd love to see more. Is there any chance that you'll be creating more videos for organic chemistry? By the way, you guys are the best! I've been using your videos for three years now.

[@houstonxue9233]

at 10:13 it says dehydrogenation is removal of a water molecule- isn't that dehydration?

[@TheCaptain14]

+Houston Xue Dehydration refers to the removal of a water molecule, while dehydrogenation refers to the removal of simply Hydrogen (H2).

[@Dan-yk9ft]

It was a typo

[@lameasspistachio]

I was just struggling while I was trying to revise my textbook. It was super boring and I don't even want to take a look at the content. Then I popped up with the idea to search some videos and i found you. THANK YOU SOOOOOOOOOOOO MUCH for helping me to learn chemistry in an interesting way

[@borntoarun]

Hank, you're awesome and everything, but at 10:14 the slide says "Dehydrogenation - removal of a water molecule." Shouldn't this be "removal of hydrogen"?

[@alara1428]

Arun Sridharan exactly my question :( too bad you didnt get an answer bro

[@peterwayne2795]

I love the energy Hank Green has in his videos

[@billiondollarbull]

How are people passing exams by just watching crash course? This merely touches the surface of what I get and doesn't help me at all with my exams. Is american education that easy? I do enjoy them though.

[@ZachGramstad]

I live in the US and I use these to introduce me to things I haven't studied yet/are about to study. There's no way someone could watch this and be ready for a test. Even in the US.

[@LeggalyBrown]

Well, it gives people a starting point of they have no idea what's going on

[@Clara-ot6bc]

Troll I think they're just exaggerating. They probably learnt the more complicated and advanced stuff in school or something but Crash Course helped summarise the basics which would help with the more advance stuff. I wouldn't feel safe at all going into the exam learning nothing but what is taught on Crash Course

[@FROPDESAI]

Troll I think the name of the commenter should give you an idea about what the comment actually is.

[@soundninja99]

Troll This gets me trough middle shcool here in Norway, nothing more.

[@jumanahidris7432]

This place is the only place I can watch a two-minute intro without getting bored.

[@arissadasa7123]

i owe you my survival in college hank thank soooo much!!!

[@enigmaxtinction5336]

Anybody watching this for homework, put the video on 1.5 or 1.25 speed. It helps the 11 minutes go faster

[@ericvilas]

Dehydrogenation - you subtitled it wrong at 10:11. Not removal of water molecules.

[@AjSmit1]

I was going to point that out too..

[@TheBlaze4000]

Are you serious? You only realized a mistake there? If you were to take out all mistakes filled in these subtitles, you'd probably might as well write out the whole thing.

[@ericvilas]

Not the captions, the actual text in the video. It said "removal of water molecules" and he said "removal of hydrogen atoms"

[@ericvilas]

***** I meant the actual thing written under the title in the video. The captions are automatic, that's not what I meant.

[@ericvilas]

Nah, it's ok, "subtitle" and "caption" are basically synonyms anyway. I should've been clearer.

[@Hambxne]

eloquently put. no chance anyone could receive an explanation this concise from our current education system.

[@thelunatic710]

I just heard "welcome to organic chemistry" and the video ended

[@John_Sturgeon]

Been a fan since I stumbled across Brotherhood 2.0, and now you're helping me study to skip Biology 101 in College. Thank you, Hank Green; this pillow on my head is for you.

[@futureDK1]

Do crash course quantum physics/mechanics!

[@Gabriela22115]

Just started Orgo in my uni and I'm beyond excited about these crash course videos! Thanks Hank!

[@Aneesh203]

Its like a puzzle we got to make. I laughed so hard on that and i don't know why!1

[@zaw408]

Hank, it says "Removal of a water molecule" und the third reaction "Dehygrogenation". Awesome episode, looking forward for more organic chemistry!

[@beatrice7873]

No matter how fast this guy goes, he's still better than my slow chemistry teacher that puts us all to sleep in class.

[@Tupster]

The nomenclature is so regular that this makes me want to write a computer program that lets you put in the name of a hydrocarbon and it will show you a 3d model.

[@Quintinohthree]

Let's see what it does to 2-vinylnaphtalene, or [2,2,2]bicyclooctane.

[@RobbieFranklin]

This program is called ChemDraw 3D

[@frollard]

See also: Wolfram Alpha - it can show what everything looks like.

[@Quintinohthree]

Jason Wilkins The former is an example of a name using nonsystematic nomenclature (because it's much easier and because, being aromatic, systematic nomenclature can't fully describe its structure), the latter an example of nomenclature you probably would miss. You'd probably eventually find some compounds for which there is as yet no known systematic nomenclature, or at least none that doesn't rely at least partially on trivial names.

[@TheRobinator143]

Trust me, that would be one hell of a program to write... Hydrocarbons are the easiest organic compounds but there are still lots of exceptions and trivial names which aren't regular. These are just alifatic hydrocarbons, when cyclic or aromatic hydrocarbons are included, things tend to get a bit more difficult. And these are only hydrocarbons, imagine the millions of other organic compounds that contain other elements like oxygen, nitrogen, sulfur,...

[@SirusDas]

when you are in search for nothing and you discover GOLD! This videos are one of them! 100% Pure Gold.

[@Derpsii]

What makes it so funny?

[@BulbulChan5]

In my school, we were taught the Calvin cycle in biology, and we had to memorize the weird names that NEVER made sense (for example: Ribulose-1,5-bisphosphate) and then AFTER we memorize calvin cycle we got to study naming organic compounds. Well done.

[@icefirexd]

too fast but explains the intro so good :3

[@cooch7112]

bless you i joined an online school late and they barely bothered helping me out. I had to teach myself everything from my textbooks. it takes so long and i am such a slacker that I never caught up. so here I am, learning my coursework on youtube for my exams next week. shouldn't have wasted my money.

I must say your videos SAVED ME! I don’t know if I’ll get a distinction but I m more certain that I’ll at least pass now! Because it’s masters level and many of my class mates are from a chemistry background I often feel stupid in class and afraid to ask questions as a result!
