A carboxyl group is a functional group consisting of a carbonyl. Its formula can be written as -COOH or -CO2H.
Amide.
Formaldehyde, as its name implies, is an aldehyde. Thus, it contains a carbonyl (CHO) functional group. This group consists of a carbon atom double bonded to an oxygen atom. The carbonyl group is the only functional group contained in formaldehyde.
The amino functional group.
Hydroxyl group, -OH
The molecule is propanone (IUPAC name) or acetone (common name) and has a ketone group (>C=O) as the functional group.
