Interpretation Introduction

Interpretation:

Derivative of carboxylic acid is ester in which the $-\text{OH}$ portion of carboxyl group is replaced by what has to be chosen from the given options.

Concept Introduction:

Carbonyl groups are the one which contain a double bond between carbon and oxygen atom.  Aldehydes and ketones possess this carbonyl functional group in it.  The structural representation of a carbonyl group can be given as shown below,

If a hydroxyl group is attached to a carbonyl group means it is known as carboxyl group.  This can be represented as shown below,

Carboxylic acid derivatives are the ones that are synthesized from or converted to a carboxylic acid.  The generalized structural representation of carboxylic acid derivatives is shown below,
