Carboxylic acid derivatives react tend to react via nucleophilic acyl substitution where the group on the acyl unit, R-C=O undergoes substitution: Study Tip: Note that unlike aldehydes and ketones, this reactivity of carboxylic acids retains the carbonyl group, C=O. .The observed reactivity order is shown below:his reactivity order is important. You should be able to understand, rationalise and use it. It is useful to view the carboxylic acid derivatives as an acyl group, R-C=O, with a different substituent attached.
