The carboxylic acid derivatives are a family of closely related functional groups:

• each contain a C=O group with a heteroatom attached

(note : this is what distinguishes them from aldehydes and ketones)
• they can all be prepared from the "parent" carboxylic acid
• on hydrolysis they all convert back to the parent carboxylic acid
• they share a common reactivity pathway with nucleophiles: nucleophilic acyl substitution.

The most important things to know about carboxylic acid derivatives are:

• how to prepare the derivatives from the carboxylic acid itself (Chapter 19)
• the relative reactivity of the carboxylic acid derivatives.
• that hydrolysis of derivatives gets you back to the carboxylic acid.
• the mechanism of nucleophilic acyl substitution.
