Alkyne Reactions & Tautomerization: Crash Course Organic Chemistry #18

[@GiorgioCapocasa]

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

[@affifahnurariani8601]

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

[@lovepeace5845]

Is there anyone who only watches these videos for fun like me? Never any exam stress, just pure pleasure. Learn, live, love. 🖖

Same, even though I'm not studying this at all (maybe in the future)

[@AliFatCat]

I'm only 12 I don't even need to know this!

[@nihaal7750]

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.

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.

I wish I had this available to me when I was taking organic chemistry.

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

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.

Thanks for posting today! Literally doing an exam on this today!

[@agbenuke]

I really love your editing. It make me stick glued to the video. Keep it up ❤❤❤🙌🙌🙌

[@Kairikey]

This series need to be binge watched lol

[@leonellin3382]

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.

[@Adaginy]

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.

[@AndyLee-p9j]

Thanks a lot!! Very helpful!

[@tommiller1315]

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 :-(

[@Soulstone961]

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.

[@JustinGabriel425]

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.

[@veil43]

ppOverheat over here going wayyyyy too fast for my slowass brain to catch up. recommend watching in x .5

[@YourWealthCome]

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.

[@sciencelover8719]

I would need that last year haha 😅🥲

[@TheRogueThunder]

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.

[@blademaster8399]

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

[@auracantikacamila7372]

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✨
