and protonated amines

The explanation:

when

The Carboxylic acids are polar . and the functional group carboxyl is formed from the hydroxyl and carbonyl group.

and about protonated amines:

-alkyl groups improve the basicity, aryl groups diminish it.

-Primary amides have an aromatic group or alkyl attached to an amino-carbonyl function.

- Primary amines are basic functions which could be protonated to the  ammonium ion
