(a)

Interpretation Introduction

Interpretation:

The given molecule is whether a carboxylic acid, an amide or an ester has to be classified.

Concept Introduction:

Carboxylic acid: One $-OH$ group is attached to the carbonyl carbon atom of the compound. It is represented as $RCOOH$

The derivatives of carboxylic acid are ester, amide

Ester: One $-OR\text{'}$ group is attached to the carbonyl carbon atom of the compound. It is represented as $RCOOR\text{'}$. The hydrogen atom of $-COOH$ is replaced by an alkyl group.

Amide: One $-N{H}_2$, $-NHR\text{'}$ or $-NR{\text{'}}_2$ group is attached to the carbonyl carbon atom of the compound. It is represented as $RCONR{\text{'}}_2$.
