Amines contains -NH2 attached to variable R (hydrocarbon) group. Describe the structure of any two categories of amines?

1. Primary amines: In primary amines, the -NH2 group is attached to a carbon atom that is only bonded to one other carbon atom. The general structure of a primary amine can be represented as R-NH2, where R is a hydrocarbon group. For example, in the case of ethylamine (C2H5NH2), the -NH2 group is attached to a carbon atom that is only bonded to one other carbon atom (ethyl group).

2. Tertiary amines: In tertiary amines, the -NH2 group is attached to a carbon atom that is bonded to three other carbon atoms. The general structure of a tertiary amine can be represented as R3N, where R is a hydrocarbon group. For example, in the case of trimethylamine (N(CH3)3), the -NH2 group is attached to a carbon atom that is bonded to three other carbon atoms (three methyl groups).
