The alkyl
derivatives of ammonia are called amine. In other words, the compounds that are
obtained when the hydrogen atoms in the ammonia molecule are replaced by an
equal number of alkyl groups. They are called amine.
They are divided
into three classes based on the number of alkyl groups associated with the
nitrogen atom in amines.
The primary amines
have only one alkyl group attached to the nitrogen atom, the secondary amines
have two alkyl groups attached to the nitrogen atom and the tertiary amines
have three alkyl groups attached to the nitrogen atom.
