More Organic Nomenclature: Heteroatom Functional Groups: Crash Course Organic Chemistry #3

[@crashcourse]

Hey everyone! This is a re-upload of last week's episode. We had the structure of one of the functional groups drawn incorrectly in one of the graphics and wanted to correct it so that students won't memorize any of this foundational information incorrectly. Thank you all for understanding and all of your support! - Hannah

[@kunalpatel2479]

I have no notes on anything except the way you pronounce Carbonyl made me have to watch that section of video like 30 times to get the content😅 love the content though extremely useful as a, well crash course… you’re well marketed…

Who is here because of Kurzgesagt?

[@Ny0s]

It says a lot that you are ready to re-upload a whole video in order to correct a mistake you made. Thank you as always, looking forward to seeing the next episode. :)

[@KillerTacos54]

Great job for re-uploading and correcting a mistake. That's some superb dedication right there. I'm looking forward to the next episode.

[@92jwiener]

Me: Pardon Barkeep, may I partake in some ethanol, hold the eth, replace with hydrogen? Bartender: One Natty Light, comin' up! Me: 😁👌

[@dadiolego]

Really well done episode, I was wondering how you guys where gonna tackle nomenclature as personally it’s one of my least liked aspects of orgo, and really imo the only way to learn it is just by doing alot of it. But I appreciate the focus on functional groups as thats the way I often end up explaining compounds to people cause no one uses IUPAC in casual conversation. Keep up the great work and this has been great for review!

[@user-vn7ce5ig1z]

Nomenclature was my favorite part of organic. People really are different. 🤷

[@shy-watcher]

Nomenclature was my favorite part of organic too, because I was a nerd and a system without exceptions has an inherent appeal. But it's still tedious to learn by heart, and delays learning everything else in the course too much IMO.

[@chuyrodriguez9646]

Im horrible when it comes to understanding chemistry, but I actually manage to soak up and learn something new with this video

[@enitmarin6805]

Los amo. Sabia que existia un error. Untedes no son asi! Un abrazo. I Love all You . Thanks for this great material. It is very useful.

[@Durrani4hmed]

When I was studying organic chemistry first time on YT, I watched this video I didn't understood anything from it as I was totally new and today I watched it all in once I understood everything shown here.. Thanks CrashCourse

[@StephenDix]

Ever drive a while and zone out and snap back in the next country over and wonder how you got there? And everybody's speaking a different language and you're on the wrong side of the road and everybody knows you don't belong there? That's how I feel when this video auto played on me.

[@FrankLeeMadeere]

Not sure if I've ever seen a better candidate for gamification! There are plenty of research articles promoting gamification of organic chem, but there are only a few basic "games" readily available to help with these concepts.

[@joshjosh6714]

Can't we call propan-2-one just propanone since the carbonyl group can't be anywhere else since there's only 3 carbons? Correct me if I'm wrong.

[@zhuochengsheng1742]

you can, it dosent matter

[@yandlurivaishnavi8595]

Hi I have a doubt, why do we write it like 2-methyl prop -2- ene -1- ol. Can you please explain me...because I have a test tomorrow

[@zahwaal-humaidan4571]

You broke it down so well! Thank you so much!

[@jonathanodude6660]

8:34 do you need the 2 in propan-2-one? the only possible configuration for a ketone in the molecule propanone is in the 2 position, so the 2 would be considered redundant.

I really love that teaching style

[@charleshain5921]

Teach us, if that’s the least you can do. God knows I can’t do any more.

[@MariaMadede]

Thank you very much.

[@sirellyn4391]

Oh actual science!! I've missed you *SO* much!! I must be in before the critical theory cultists have had their way chemistry. I'm so sorry evolutionary biology... We thought after you survived creationism you could survive anything... How wrong we were...

[@davebalaam]

OK, so quick question: Pentan-1-ol is Pentane with an OH group on the first carbon atom. Ethanol is Ethane with an OH group on the first carbon atom... so why does Pentan-1-ol include the 1, and Ethanol doesn't? Should it be Ethan-1-ol, or can Pentan-1-ol be shortened to Pentanol?

[@Quintinohthree]

There is also pentan-2-ol and pentan-3-ol but there is no ethan-2-ol, so you don't need to specify ethan-1-ol, ethanol is sufficient.

[@DmasterX69]

Cause ethanol has two carbons. So whichever carbon has the OH group, that carbon will be assigned the number 1 Then when you hit 3 carbon alcohols you start getting the combinations. Propan-1-ol and Propan-2-ol as the OH Group can either be on carbon 1 or carbon 2. With 4 carbons, you get Butan-1-ol, Butan-2-ol, and Butan-3-ol, since you can have an OH group on carbons 1,2, or 3. And so on...

[@Quintinohthree]

@@DmasterX69 Butan-3-ol actually is butan-2-ol again.

[@enigmaticidez9839]

Does it matter if we use a superscript or subscript number? 7:03 has a contradicting audio script and drawing.

[@jonathanodude6660]

numbers are usually subscript, i dont think its really thought about by scientists. we could also use apostrophes which would be read "R prime"

[@Skidmark75]

I wonder if she works out? She has nice traps and shoulders.

[@ilikedota5]

don't amides have hydrogens as the to R's attached to the nitrogen? That doesn't look right...

[@arielthomas8737]

amides vs amines

[@jlaetsch3]

The R-groups on amides can be either hydrogens or alkyl groups. Primary amides have hydrogen on both R-groups, but secondary amides have one hydrogen and one alkyl group, and tertiary amides have two alkyl groups. R-groups are sometimes only used to mean alkyl chains, sometimes to represent any group (including hydrogens). It depends on who draws the structures. My OChem textbook always specified -H or -R, but my professor used -R for both as a shorthand.

IMO it only really makes sense to learn this if you want to study it (unless you are interested in it), I doubt you would get a job after only learning the basics. So, are you people watching this because you have to learn it for school/university or simply out of interest?

[@PyroOfMalice]

I'm watching this out of pure interest because I think it's pretty important to understand the chemistry of things that are important to our modern civilization.

There's tho much ethanol in my blood to remember this.

[@shy-watcher]

I feel like following the standard organic chemistry path (start with nomenclature, bore everyone by the third lecture because it's just grammar without the poetry, do whatever else (I honestly don't remember how our organic chemistry classes continued after that, I was bored)) was a mistake for this series. It just feels like a standard course with charisma and production value, which is not enough. The standard organic chemistry course needs a structural change.

[@robelbelay4065]

I am grateful for the charisma and production value but yes I agree with you. It feels like learning about screwdrivers and hammers without knowing when, how, and for what they are useful. I think I am searching for some way to have organic chemistry be taught in action, perhaps diving into functional groups one at a time and explaining the reason and ways they are reactive. I am self-learning so I am skipping around in a book and willing to wait until crash course is past the nomenclature to decide if they did it differently. However, I think their target audience is students in a standard organic chemistry course so perhaps this is meant to be an aide to them. Outside of that context however, the specific names are something one would just google rather than memorize.

[@amiteashpaul]

CrashCourse's target audience is high school students who are currently studying the subject (here, Organic Chemistry). For them, it is important that the course starts with nomenclature and then follows up with reactions etc. so that they can reinforce what they learn in their course. I agree with you that schools should take different functional groups separately - discussing nomenclature, properties, preparation, reactions etc., before moving to the next functional group. In fact, that's how we learn Organic Chemistry in India. In Class 11 (Junior Year), we learn about the Basic Rules of Nomenclature (suffixes, prefixes, numbering etc.), followed by "Alkanes, Alkenes and Alkynes". In Grade 12 (Senior Year), we have separate chapters for "Alkyl and Aryl Halides", "Alcohols, Phenols and Ethers", "Carbonyl Compounds and Carboxylic Acids" and "Amines". Each chapter starts with nomenclature, followed by properties, preparation, and reactions for one/two functional group(s) only.
