Phase 1: Mechanism Comprehension The process adheres to oxymercuration-demercuration, characterized by an anti-Markovnikov addition of alcohol. A mercurinium ion arises as an intermediate, subsequently attacked by methanol (\( CH_3OH \)). Phase 2: Reduction via NaBH4 The \( Hg(OCOCH_3) \) moiety is substituted with a hydrogen atom. The end product incorporates an ether functional group (\( CH_3OCH_2- \)). Conclusion: The resultant compound is an ether.
