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
Brooklynn B Don’t give up! I’m finding this hard too, but you will do it? How did you do on your exams? I bet you passed. Do not give up, because that is worst thing you can do. I believe in you
@@tomatrix7525 hiiii i never saw this! i passed orgo with a B 😭 and now i’m in grad school and THIS is where i give up 🤣🤣🤣 jk thank you for your kind words 😍🥺💕
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
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
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?
on 2:23 you talk about the resonance structures of the alkene mercury acetate compound but then u start breaking sigma bonds and the octete rule which wouldn't make what you drew valid resonance structures, I am very confused as to why you did that maybe it was just a mistake or I'm missing something.
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 😅😅😢😢😢

3:32 , The 2nd resonating has 3 membered ring it then how can it be said as more stabl?

Prof lecture + this vid = perfection
After multiple lectures I never understood this but in 90 seconds you made it make sense. God bless you man
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
How'd the next one go?
this is where i give up
Brooklynn B Don’t give up! I’m finding this hard too, but you will do it? How did you do on your exams? I bet you passed. Do not give up, because that is worst thing you can do. I believe in you
@@tomatrix7525 that was really wholesome

dont !!!!

your teaching is lucid clear

[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
I love your teaching, you help me for many things.
welcome
Things starting to get interesting!
by May 2021 you will be at 3M subs
3 years later in 2024… almost 8M
sir
you must add THF to H2o
to make a reaction
Thank you, the problems helped a lot!
welcome

no space for h2o to attack
man I love you
Thanks man
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?
My prof said no rearrangement for these reactions. Don’t ask me why … I’ve just accepted it and committed it to memory 😂
Why mercury has more than 2 valence electrons?
Thank you so much!!
Why didn't you do a ring expansion for the vinyl pentene and mercury acetate with sodium borohydride reaction

because we dont do rearrangement on the oxymercuration - demercuration
