Holy crud I might cry, it's near the end of the semester and I've discovered this guy's Ochem full playlist. I will watch these and study them for my primary ochem knowledge through the end of ochem 1 and all of ochem 2. He even made final exam reviews for both...OChem tutor, you are my hero now, I'm not even kidding, I am on the verge of tears of relief

this is where i give up

Prof lecture + this vid = perfection

I am surprised this series has such few views. This guy has helped us all.

I did poorly on my first exam but your videos are helping me keep up. Thank you for the help boss

After multiple lectures I never understood this but in 90 seconds you made it make sense. God bless you man

The video explains the oxymercuration-demercuration reaction of alkenes, its regioselectivity, and mechanism. It also provides a practice problem and offers100 multiple choice problems for a chemistry final exam. [00:00] The video explains the oxymercuration demercuration reaction of alkanes - The reaction involves reacting an alkene with mercury two acetate and water - The oxymercuration step adds an OH group to the more substituted carbon and mercury to the less substituted carbon - The demercuration step removes the mercury and replaces it with a hydrogen atom using sodium borohydride - The mechanism involves the ionization of mercury acetate, attack of the alkene on the mercury atom, and stabilization of the intermediate by resonance [03:00] Oxymercuration reaction produces a racemic mixture of both R and S two-butanol. - Secondary carbons with a positive charge are more stable than primary carbons - The major resonance contributor is the most stable resonance structure - Water attacks the secondary carbon atom due to its higher partial positive charge - The oxymercuration step involves using a base to remove a hydrogen atom - Sodium borohydride is added in the final step to get the alcohol product [06:05] Oxymercuration reaction does not undergo rearrangement and results in OH group on more substituted carbon atom of double bond - No rearrangement occurs in oxymercuration reaction - OH group is added to the more substituted carbon atom of the double bond - Results in a racemic mixture of products [09:05] The oxymercuration reaction results in anti-addition and can produce enantiomers - The O-H group and mercury acetate group must be on opposite sides - The alcohol group can be placed on either carbon atom of the double bond - For a non-chiral carbon, only one stereoisomer is produced - For a chiral carbon, two stereoisomers can be produced with the O-H group on the wedge or dash

your teaching is lucid clear

The key with OCM watch and practice as much as possible ..expose yourself ..otherwise just watching without doing anything is risking....I watched this video first time it was hardddd ..but the more I practiced the more I got the drift and remembered what The OCM tutor was sayin in this video ..dont be lazy lol ..just practice

I love your teaching, you help me for many things.

Things starting to get interesting!

Why aren't we doing ring expansion at 8:30?

Thank you so much sir

sir you must add THF to H2o to make a reaction

Thank you, the problems helped a lot!

Thank you so much for making this video

Super helpful video. Thank you so much!

Sir, in the hybrid structure, the +ve charge on Hg>+ve charge on 2°C atom>+ve charge on 1°C atom.Now,H2O is a nucleophile.Then it should attack the most electron deficient region of the hybrid that is, the Hg atom.But instead of that it attacks the 2°C atom.Why is this so?Could you explain?

Why mercury has more than 2 valence electrons?

Why didn't you do a ring expansion for the vinyl pentene and mercury acetate with sodium borohydride reaction

In the first example, why did the carbocation not shift to the left since it has more alpha-H and will be stabilized by hyper-conjugation?

ong this guy deserves more

I love your teaching

by May 2021 you will be at 3M subs

What is the product formed when i carry out oxymercuration-demercuration hydration of a benzyl methyl ketone like 1-phenyl-3-butanone?

What about the intramolecular capture of mercuronium salt?

11:31 is first one major due to inductive effect stabilizing carbocation?

sir pls my question is, are the acetate and the mecury gonna form part of the products for the anti addition?

CH3-CH2-CH(OH)-CH2(HgOAc) Как называется это вещество?

Thank you so much!!

Thanks man

man I love you

are we always adding OH

why wouldn't the cyclopentane under go a ring expansion during the time there is a carbocation intermediate?

methyl shift?? 8:20

On the problem of 7:33, why can't you do a methyl shift?

I love you really ❤️

How old are you?

mercuric acetate with water without THF does not make any reaction

Can someone explain to me why there is no ring expansion at 8:45 ?

Was the reaction at 11:28 correct?

My exams in 6 hours.. I feel like I’m gonna get a 5 a literal 5. Wish me luck I’ll update with the score tomorrow. I need a 25 to pass and idk if I’m even gonna get it 😅😅😢😢😢

Great

Can somebody help Me? !! My exam is tomorrow 😭

❤️

Nyc

Damn
