Step-by-Step SolutionStep 1: Reactions of epoxides

Due to the steric strain in the epoxide ring, it readily participates in reactions with strong acids and with nucleophiles.

Neutral nucleophiles on reaction with epoxide and will attach at more substituted carbon of epoxide whereas negatively charged nucleophiles will be attached at less substituted carbon of the epoxide.

Explanation

The cyclic ether epoxide gets open on reaction with HBr ethoxide ion/ethanol in the presence of water and NaCN in the presence of water and forms the respective product that consists of –OH group.

The products of the given reactions are as shown below:

a.

Formation of products in reaction a

b.

Formation of products in reaction b

c.

Formation of products in reaction c

d.

Formation of products in reaction d
