Step-by-step solution

Introduction. (part  a)

Simple amines are given common names. When two or more alkyl or aryl groups are bound to the nitrogen atom in a compound, they are listed alphabetically. Di and tri are prefixes that denote two or three identical substituents.

Given Information (part a).

To find the common name.

Explanation (part a). 

The following is the structure of the given compound:

The compound contains a propyl group $\left(-{\mathrm{CH}}_2-{\mathrm{CH}}_2-{\mathrm{CH}}_3\right),$that is connected to the nitrogen atom of the amine group.

As a result, propylamine is the common name for this compound.

Given Information (part b).

To find the common name.

Explanation (part b). 

The following is the structure of the given compound:

The amine group's nitrogen atom is linked to the methyl group $\left(-{\mathrm{CH}}_3\right)$and the propyl group$\left(-{\mathrm{CH}}_2-{\mathrm{CH}}_2-{\mathrm{CH}}_3\right).$

This compound is also known as methyl propylamine.

Given Information (part c).

To find the common name.

Explanation (part c).

The following is the structure of the given compound:

One methyl group $(-C{H}_3)$and two ethyl groups $(-C{H}_2-C{H}_3)$ are tethered to the nitrogen atom of the amine group in this compound.

As a result, diethyl methylamine is the common name for this compound.
