Step-by-step solution

Step-by-Step SolutionStep 1: Nucleophilic substitution reaction

The organic reaction involving the attack of an electron-rich nucleophile at the electrophile to displace a leaving group is known as a nucleophilic substitution reaction.

The given nucleophilic substitution reactions a and b

a. As a strong nucleophile, the acetylide anion attacks the electrophilic carbon replacing the chloride anion from the least hindered side. The stereochemistry of the product would be the same as the reactant.

The product formed in reaction a

b. The strong nucleophile would attack the carbon, displacing the leaving group in a bimolecular nucleophilic substitution reaction.

The product formed in reaction b

Hydration in reactions c and d

The reaction involving the combination with water molecules is known as hydration.

The intermediates in c. and d. would undergo hydration to give the corresponding enantiomeric mixture of alcohols.
