Step 1: Understand what an amine is. An amine is a compound that contains a nitrogen atom (N) bonded to carbon atoms (C).
Step 2: Know the types of amines. There are three types: primary amines (one carbon group attached), secondary amines (two carbon groups attached), and tertiary amines (three carbon groups attached).
Step 3: Identify the structure of dimethylamine. Dimethylamine has the formula (CH3)2NH, which means it has two methyl (CH3) groups attached to the nitrogen atom.
Step 4: Determine the type of amine. Since dimethylamine has two carbon groups (the two methyl groups) attached to the nitrogen, it is classified as a secondary amine.
