As an organic chemist, I decided to watch this for fun while having breakfast. I quickly found myself glued to the screen! The explanation is so clear and elegant, yet thorough enough to help you pass an organic chemistry 101 exam; the illustrations are really high quality and the animation really helps with understanding electron pushing. I feel like some university level organic chemistry lectures would greatly be improved if the teacher just played this video at half-speed. I'll definitely be watching more of these. Huge thanks to the whole Crash Course team!
As a student in chemistry, I dedided watch this video not only as a media for my study when facing exams, but I also see it to see how to explain material in a very fun and enjoyable way for my students in the future. Seeing the comments sections makes me even more sure that students are happy with fun learning chemistry on this way like this
A quick note on hydroboration-oxidation: typically, disiamylborane (a "bulkier" variation of borane) is used to prevent the formation of messy product mixtures. Since alkynes have two pi bonds and can react twice, a reaction with borane causes unwanted, extra additions. However, the steric hindrance from using disiamylborane prevents such extraneous additions from happening. Therefore, disiamylborane is useful in hydroboration-oxidation because the reaction would only yield one major organic product, which is typically desired.
LOVE THIS! Can you PLEASE do a video about Palythoa Toxica? My little girls and I almost died from an airborne toxin/ coral polyp in my reef tank, and NO ONE in the hospital knew how to help us.
What’s it like being able to watch this without getting flashbacks to how traumatic organic chemistry was? It’s a fun subject but not when you’re competing with pre-meds for a good grade.
Love Peace - Is there anyone who only watches these videos for fun like me? Totally! Wish I'd had more organic chemistry in 1970!!! My tutor vanished for 6 months so I didn't get past the methane / ethane / ... isobutane etcetera starter :-(
my brethren of the earth, I haven’t studied and I have an exam in 3 days. Cross your fingers i get out of this depressive episode soon so I can do more than watch a video to study.
For the base-catalyzed tautomerization reaction, wouldn't it be inaccurate to use BH3? BH3 can perform the addition twice, so in order to prevent this from happening wouldn't you need a larger boron compound with two large substituents? Like disiamylborane? A larger boron molecule would mean more steric hindrance and ensure water doesn't add across the alkyne twice and you get the desired product, unlike with BH3.
Yaps, keto-enol tautomerism is the most common tautomerism. Keto-enol tautomerism refers to a chemical equilibrium between a keto form (a ketone or an aldehyde) and an enol (an alcohol). The keto and enol forms are said to be tautomers of each other. For example, aseton. Acetone is the simplest of ketones, used as a polar solvent in most organic reactions. Acetone has acidic hydrogen atoms, so it can ionize to produce enolate ions. Enolat ions can be in two forms, it's keto and enol. I'm sorry, if my answer is incorrect, please correct it. Thank you✨
@ 3:42 What's with the playschool microscope? Objective lenses are an inch above the slide. So i guess this purple prop is to connote SCIENCE? Too silly

Is there anyone who only watches these videos for fun like me? Never any exam stress, just pure pleasure. Learn, live, love. 🖖
welcome to "Nerdfighteria"
DFTBA
Same, even though I'm not studying this at all (maybe in the future)
I'm only 12 I don't even need to know this!
Yea maybe u can say so cuz u ve already learnt this. It takes me two to three re watches to appreciate what they are trying to convey.

Yes, as a medical student i agree with u. This video makes study organic chemistry so much fun and easier

I wish I had this available to me when I was taking organic chemistry.
Same
Crash course the best
Com certeza 👉👍
God this series just makes me remember why I failed chemistry in highschool 😂
My final is tomorrow and I got a 29 on my last test send prayers
Just a few days too late for the exam :(
5 hours ago for me 😔
One year to late for me lmao 🤣
LOVE THIS! Can you PLEASE do a video about Palythoa Toxica? My little girls and I almost died from an airborne toxin/ coral polyp in my reef tank, and NO ONE in the hospital knew how to help us.
I really love your editing. It make me stick glued to the video.
Keep it up ❤❤❤🙌🙌🙌
Thanks for posting today! Literally doing an exam on this today!
Thanks a lot!! Very helpful!
Some days you're an enol and some days you're a keto, you know?
This series need to be binge watched lol
8:53 “pissed-off intermediate” 😂😂
😆 *pit stop intermediate

These have been too dense for me for about 10 episodes, but I do like watching the first few minutes to learn about real world applications.
You should do Aztec mythology
Hi thanks for finding you you are awesome and your lesson are helpful
A video on Haloalkanes and Haloarenes please.
It's 5.30 am at india 🇮🇳 dude
Cool!

What a great explanation!!!
Like if you think crash course is life saving
ppOverheat over here going wayyyyy too fast for my slowass brain to catch up. recommend watching in x .5
If you think this is fast watch the crash course chemistry with Hank... I had to hit the 10 rewind and pause a-lot! He was a really fast talker.
I would need that last year haha 😅🥲
cool
Wheres john amd hank tho
Constructive feedback: I would have loved for this to be, say 14 minutes and move slightly slower. Watching on .75 speed with lots of pausing.
Final exam tmr!
Notice me🙋🏻♂️

Yay , commenting for the algorithm
Keto-enol tautomerism is the most common tautomer couple, right? What's the compound example?

I'm just studying 9th grade but I feel Organic chemistry is lot more fun.
Petition for a Music Theory Crash Course
Bucky ball
how old are yall 😩😩
She's looking like Camila Cabello to me
dope
Talks too fast!
Agreed
too
I’m just sad frogs are dying out
I need the 0.75x speed button but I can't find it
Ahahaha I chose the wrong major - fml
Same with me, bruh haha
