Carboxylic acids contain the carboxyl functional group, -COOH, which is itself made from a carbonyl group and a hydroxyl group.
Molecules derived from carboxylic acids have replaced the -OH group with
- -Cl in acyl chlorides
- -NH2 in primary amides
- -NHR in secondary amides
- -NR2 in tertiary amides
- -OR in esters
- -OCOR in acid anhydrides
You need to be able to recognise all of these functional groups and name simple examples of each.
