(a)

Interpretation Introduction

Interpretation: The products for the given reactions to be identified.

Concept Introduction:

Ring-opening of epoxide: The epoxide ring is highly strain and readily undergoes reaction with strong nucleophile result in the ring-opening reaction.

Regiochemistry: when the epoxide is unsymmetrical, the nucleophile attack at the less substituted position.

Stereochemistry: when the nucleophile attack takes place at chiral center, an inversion of configuration is obtained.

Alkoxymercuration-demercuration: the process where alcohols can be prepared from alkene, results in the markovnikov’s addition of H& OH groups across the double bond of alkene.

Useful reagents:

  1. 1. NaSH : A very strong nucleophile that will react with an epoxide in a ring-opening reaction.
