(a)

Interpretation Introduction

Interpretation:

The parent heterocyclic base in the given compound has to be determined.

Concept introduction:

Amines are the derivatives of ammonia $\left(N{H}_3\right)$ with one or more of the hydrogens replaced with a substituent such as an alkyl group.

Heterocyclic amine is a five or six membered cyclic organic compound which contains one or more nitrogen atoms.

Interpretation Introduction

Interpretation:

The functional groups present in the given compound acyclovir should be identified.

Concept introduction:

Organic compounds are classified by the presence of characteristic functional groups.

A functional group is an atom or a group of atoms other than a $C-CorC-H$ bond. It is the reactive part of the molecule and important to determining its physical properties.

Functional groups have a specific characteristics, name, formula and structure.

Some functional groups are listed below,

$\begin{array}{cc}Name& Functionalgroup\\ Alcohols& R-OH\\ Ethers& R-O-R^{\text{'}}\\ Aldehydes& R-CHO\\ Amide& R-NHCO-R^{\text{'}}\\ A\min e& R-N{H}_2,R_{2}NH,R_{3}N\end{array}$
