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

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

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.

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?
