Step-by-step solution

Alcohols from alkenes

Alcohols can be prepared from alkenes by using oxymercuration-demercuration reactions.These electrophilic addition reactions are a two-step pathway for obtaining alcohol.

Preparation of alcohol from an alkene

a) The given alcohol can be prepared when 2-methylhex-2-ene or 2-methylhex-1-ene is treated with $\mathrm{Hg}{\left(\mathrm{OAc}\right)}_2$, and water reacts with more substituted carbon. The proton transfer takes place, and at last, demercuration occurs via reduction.
