a)

b)

c)

Short answer

Part a) Aniline is the common name for the compound.

Part b) Cyclopentylamine is the common name for the compound.

Part c) Dipropylamine is the common name for the chemical.

Step-by-step solution

Step - 1 Introduction (Part a)

• Primary $\left\{1°\right\}$amines are those in which the nitrogen atom is linked to only one alkyl group.
• $\left(2°\right)$amines with two alkyl groups bound to the nitrogen atom.
• $\left(3^0\right)$ Three alkyl groups are provided a nitrogen atom in tertiary amines.

Step -2 given information (part-a)

$aniline$

Step - 3  Explanation (part- a)

• The compound's common name is aniline. It's a tertiary$\left(3°\right)$amine.
• In this structure, one alkyl group is connected to the nitrogen atom.

Step - 4  Given information (part- b)

Step-5  Explanation (part-b)

• The compound's common name is cyclopentylamine. It's a $\left(1°\right)$primary amine.
• The nitrogen atom is linked to one alkyl group in this structure.

Step-6 Given information (part-c)

step-7 Explanation (part-c)

• Dipropylamine is the chemical's common name.
• It's a $\left(2°\right)$econdary amine. The nitrogen atom is linked to two propyl groups in this structure.
