Answer: (D)

Verified step by step guidance

1. Identify the functional groups present in the molecule. In the given structure, there is an amine group (NH) attached to a benzene ring, and an isopropyl group attached to the nitrogen atom of the amine.
2. Recognize the parent structure. The benzene ring with an amine group attached is known as aniline. Therefore, the base name of the compound is derived from aniline.
3. Determine the substituents on the nitrogen atom. Here, the nitrogen atom of the amine group is bonded to an isopropyl group, which is a common alkyl substituent.
4. Apply the IUPAC naming rules for amines. When naming secondary amines, the substituents on the nitrogen are prefixed with 'N-' to indicate their attachment to the nitrogen atom. In this case, the isopropyl group is attached to the nitrogen, so it is named as 'N-isopropyl'.
5. Combine the names of the substituents and the parent structure. The complete IUPAC name for the molecule is 'N-isopropylbenzenamine', indicating an isopropyl group attached to the nitrogen of an aniline structure.
