Explanation of Solution

Primary amines are those compounds in which one of the hydrogen atoms of ammonia is replaced by an alkyl or aryl group. They are represented as RNH2

The carbon atom attach to four different group is called a chiral atom. When a molecule possesses such atom, then they are not superimposable on their mirror image.

The molecular formula C4 H11 N is 10 on the aliphatic amine, and it is a chiral molecule. Hence, the chiral carbon atom is attached to four different groups, which include -NH2 group, the -CH3 group, the -CH2 group and the -H group. The structural formula of C4 H11 N is as below:

Explanation of Solution

Quaternary amines are those compounds in which all four of the hydrogen atoms of the ammonium ion are replaced by an alkyl or aryl group. It is an ionic quaternary salt.

When the carbon atom is attached to four different groups, it is called a chiral atom. When a molecule possesses such an atom, then it is not super imposable on its mirror image.

The molecular formula C9 H22 NCl is a quaternary amine and it is a chiral molecule. Hence, the chiral nitrogen atom is attached to four different groups, which include -CH2 CH3 group, the -CH2 CH2 CH3 group, the -CH3 CHCH3 group, and the -CH3 group. Therefore, the quaternary ammonium salt of C9 H22 NCl is as below:
