Oxymercuration-Demercuration

The video tutorial explains the oxymercuration-demercuration reaction, a two-step process involving mercury acetate and sodium borohydride, resulting in Markovnikov hydration without carbocation rearrangement. The mechanism is similar to halo hydrogen formation, producing a racemic mixture. Variations like alkoxymercuration-demercuration are also discussed, highlighting their use in ether synthesis.

What is the role of sodium borohydride in the second step of the reaction?

What is alkoxymercuration-demercuration and how does it differ from oxymercuration-demercuration?

Discuss the importance of avoiding carbocation rearrangement in the oxymercuration-demercuration process.
