Question

Given below are two statements:
Statement I:

IUPAC name of Compound A is 4-chloro-1, 3-dinitrobenzene.
Statement II:

IUPAC name of Compound B is 4-ethyl-2-methylaniline.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are correct
• B. Statement I is incorrect but Statement II is correct
• C. Statement I is correct but Statement II is incorrect
• D. Both Statement I and Statement II are incorrect

Answer 1

The Correct Option is B

To evaluate the IUPAC nomenclature of the provided compounds and confirm the veracity of the assertions, an analysis of each compound is necessary:

1. Compound A

The structure comprises:

• A chlorine atom (Cl) bonded to a benzene ring.
• Two nitro functional groups (NO₂).

1. Compound B

The structure comprises:

• An amino group (NH₂) attached to a benzene ring, establishing benzene as the parent structure.
• Methyl (CH₃) and ethyl (C₂H₅) substituents.

Following the preceding analysis, the accurate conclusion is:

• Assertion I is erroneous, whereas Assertion II is accurate.
