@@hennessy_aj i'm more concerned by it's lack of sense...

[@gangsterkoala1]

“It’s either an ether or an ester, either ester or ether, ether or ester either one, one or the other, either ether or ester!” 😂 This had me cracking up, so thankful for Hank Greene🙏

[@SteveSimi]

You should do a crash course in organic chemistry...Hank you are literally the greatest teacher I've ever had!

[@orangemushroominfield]

like haloalkanes and whatnot... a crash course on those would be so useful

[@ok3892]

They are doing one now!

[@isa.sharif]

I studied this in school in the whole past month, and now you made it all fit in a 8:37 minutes long video. School is so boring, and even more boring and useless when there are good videos like this one.

[@Yuno08888]

still the depth your school is providing you while teaching you these stuff is important. These are like..the very basics about a portion of hydrocarbon derivatives

[@isa.sharif]

@@Yuno08888 Wow! I wrote this comment in my last year of high school, and now I'm in my last year of college, becoming a doctor in a few months.. Only god knows how bad I miss those school days 😢 Thank you for reminding me of this comment 😊

[@Yuno08888]

@@isa.sharif I'm in my last year of highschool as well! Hopefully i can become a doctor as well Congratz dude I wish you all the best♥

[@HerTheOneAndOnly]

I just love hank- whenever I start dozing off, he cracks a joke. " Methanol absolutely will kill you"

[@gokucrazy22]

Organic Chemistry is like a fun puzzle and a lot of wordplay. When I solve organic chemistry problems, I feel like I'm sherlock holmes or something XD

[@devasmitakundu8874]

Have you studied all the reaction (example - Friedel crafts alkylation reaction, acetylation reaction, clemensen reduction reaction, bayer's test, wolf-kishner reaction, wurtz reaction, mozingo reduction)????????

[@humixmusic4lyf]

5:20 - more than twice mate -__-'

[@JTan-wu7wg]

Cadaverine? Sounds good for an extreme metal band.

[@toniisaurVODS]

seeing the connections between functional groups makes me so happy. i never saw this before. thank you 😭❤️

[@celestesajik9926]

who else is watching this an hour before their exam?

[@danielashe835]

I am right now! All 6 lessons for organic chem. Maybe ill get it before i write

[@jae9169]

2 hours left for me

[@bryonrusselmatias9362]

Celeste Saji K a presentation, science presentation

[@choasslave4608]

Watching this because I'm gonna make a letter with 300 to 500 words in it :/

[@zainbenten4423]

4 days prior lol

[@Wilc0]

having a BSc in chemistry, I could follow you without problems, but I can imagine others had to pause/rewind the video multiple times to understand it. Good of you to not explain things slowly, that is the magic of online videos! If you don't understand, just pause and rewind until you do!

[@infamous2477]

when you talk,chemistry makes sense. i wish you taught at my school.

[@amitsanjeev2135]

Same..... My teachers are nothing like this

[@alyssacleland]

Seriously had these all memoried after watching twice. And was quite entertained along the way. BRAVO

[@luoana7574]

I think his videos are amazing, I keep rewatching them just because I love the way he explains himself

[@salomeebegue9144]

Thank you so much once again to all the team for these videos, you make my chemistry classes fun and fascinating :)

[@schlondpoofa529]

i like it when he said amino acids which make up protein which make up you which is pretty important. i have never felt so important i love you hank

[@quantusmechanicus5921]

I'm in 9th Grade and using these videos to review for the finals. Very effective. Just drop me out of school and I'll watch these videos and I'll learn everything.

[@ielizabethm2]

I love this, if I watch this a couple more times to understand organic chemistry, I would ace my test on it! Wonderful.

[@alexminser1482]

Thanks for the videos Hank this is exactly what we need to know for my chemistry class right now

[@lulufaisal7691]

Loveddddd ittttttt 😍❤️ I really understood what's a functional group is thanxxxx❤️❤️❤️

[@TechLaboratories]

It's nice that all the names of the functional groups are related. Nice, that is, once you UNDERSTAND the groups. On the other hand, it adds to the difficulty in learning their names, one of the biggest reasons many people struggle with organic chemistry, since they are so close that they are really, really easy to muddle in the brain, i.e. it takes a ton of brain work and repetition to keep those memory pathways separate instead of blurring into on big mush of carboalcoacetonahyde...

[@nessaashdivas]

Hank, you made my heart smile when you said you were a dork. You are the cutest

[@turdl38]

I don't know what a script supervisor does, but I always picture a stack of papers sprouting legs and trying to run off then that person grabbing it before it can get anywhere.

I'm telling you hank you're ah literal life saver.. Thank you

[@the-thane]

Thanks again for such a great video, Hank.

[@amyh475]

crash course chemistry, you are a beautiful thing. Saving my procrastinating butt on the day of an exam. Thank you for these videos.

[@jtasker100]

This videos sums up the part of A-level Chemistry i was good at. After 4 years i want to find my old text books and see what i remember.

[@rileypurcell2159]

Hank was right if you watch it twice it makes a lot more sense

[@lifeonlowbatteries8153]

I love that this channel is subtitled so well. Both because you babble unbelievably quickly (assuming in order to meet time constraints) and because it helps me to read things as I learn them.

[@anacorrea1821]

Hank you're hilarious, I love functional groups too....watched it just for fun

[@android19willpwn]

god, I am never gonna remember all this on my test tomorrow. Time to watch again.

[@theprinterlady]

First time the functional groups have made sense to me. Thank you.

[@nicole-su8dl]

YESYESYES i have an exam tomorrow and this was literally the only thing i didnt understand.. love crashcourse!!

[@Officer.K.]

I take a chemistry course in school and yet I don’t go into these videos with a revision session mindset. Instead I like to watch these out of curiosity. A wise man once said “you never learn something as profoundly as when it’s purely from curiosity”.

[@celestehills]

Much much better than the lectures I'm taking in college (y) when Hank explained aldehyde I was like OOOOOOOH now I seeee

[@AlexTheMary]

This video made me super excited for chemistry!!!!!

[@PepitoYT_]

Pretty hardcore video (in a good way!), definitely worth another watch. Thanks!

[@levelfivegymnast]

actually a life saver thank you!

[@youssefmosleh9547]

Oh and you're explanation is really good keep going mate 😅

[@NoelleCho]

Wow. It really helps! Thanks crash course!

[@Evipicc]

when I was younger I was fascinated with how horribly toxic, poisonous or even radioactive atoms could be combined with other atoms of the same properties, such as cyanide then all of the sudden you get a vitamin or protein that is important for life.

[@RexGalilae]

It's been years and I'm still waiting for a crash course series on organic chemistry

PERFECT TIMING I sighed and decided to watch it again thats EXACTLYwhen he assured me !

[@sheenakorah8588]

I actually watched it thrice

[@user-be4yc2vr5c]

he lied

[@Marinealver]

He said watch it again to understand it so I watched it again.

[@davidcheese1032]

***** the ultimate question do you understand it now?

[@Marinealver]

just the most rudimentary parts of it.

haha like how quickly he's talking cos it helps save a lot of time :)

[@manicpixiedreamgirl7930]

Thank you!

[@m0cean]

i love you hank

[@peas320]

There's also Amides. If you throw an Amine group onto the end of a carbonyl group (to replace the second R group) you get an Amide! :)

[@thepootrickshow]

Very Helpful! thank you. :)

1:19 Yay! Trinitrotoluene!! Been waiting for that to make an appearance... :D

[@abdallababikir4473]

TnT huh

[@jfortman73]

Makes me wish I'd taken Organic Chemistry in school when I was taking random classes. While the basics were pretty straight forward, the terminology made my eyes water. Or maybe that was onions being chopped in the next room.

[@nicholashill9858]

Might be important to state that alcohols can be put in to three classifications: Primary, Secondary and Tertiary alcohols. This basically tells you how many radicals (Rs) are connected to the carbon that holds the important stuff (oxygen and hydrogen in this case), the functional group. When you dehydrogenate a Primary Alcohol you get an Aldehyde, which you then again can dehydrogenate to make a carboxylic acid. A secondary alcohol can be dehydrogenated into a Ketone, and a tertiary cannot be dehydrogenated at all. This might make it easier for some people to understand this topic, as it helps me. Also to clearly explain the primary and secondary bit: if there's only 1 radical (R) connected to the relevant carbon, it's a primary alcohol, if there are 2 radicals connected it's secondary and so on. it cannot exceed a tertiary alcohol though. Hope this helps someone! :)

[@charliemilarvie902]

can you not just say oxidised rather than dehydrogenating?

[@nawalzahra2106]

Thanks man 🙏🏻🙏🏻🙏🏻

[@andregrundy3680]

First video I'm watching. I'm a chemist and was thinking HOW did you make it 43 episodes without mentioning any compounds with elements besides carbon and hydrogen!?!

[@vikrampinto]

wow thank you so much

[@MrHtoo2]

I wish I found these videos my freshman year. I wouldn't be so bored by chemistry.

[@sherif1875]

5:20 "I swear if you watch this episode twice, you will understand" Watched twice, can confirm
