(a)

Interpretation Introduction

Interpretation:

Structural formulas for A and B has to be proposed.

Concept Introduction:

The hydrolysis reaction of alkyl nitrile in presence of acid is written as,

(b)

Interpretation Introduction

Interpretation:

Mechanism for the formation of A has to be proposed.

Concept introduction:

Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of chemical bond.

Electrophile: It is positively charged species which seeks for negative charge and hence accepts pair of electrons from negatively charged species (Nucleophiles) which results in the formation of chemical bond.
