Question

Consider following statements.
S1: IUPAC name is 4-chloro-1,3-dinitrobenzene
S2: IUPAC name is 2-methylaniline

• A. Both S-1 and S-2 are correct
• B. S-1 is correct, S-2 is incorrect
• C. S-1 is incorrect, S-2 is correct
• D. Both S-1 and S-2 are incorrect

Answer 1

The Correct Option is C

To determine the accuracy of the statements, we need to analyze the provided images and their corresponding IUPAC names.

1. Let's consider Statement S1:

Analysis of S1: The image shows a benzene ring with chlorine and two nitro groups. Numbering should be done to give the substituents the lowest possible numbers.

This structure is better named as 1-chloro-2,4-dinitrobenzene, not 4-chloro-1,3-dinitrobenzene.

2. Now, consider Statement S2:

Analysis of S2: The image shows an aniline (amino-benzene) derivative with a methyl group. The correct IUPAC name is indeed 2-methylaniline.

Thus, based on the analysis:

• S1 is incorrect because the correct IUPAC name should be 1-chloro-2,4-dinitrobenzene.
• S2 is correct as the structure matches 2-methylaniline.

Conclusion: The correct answer is S-1 is incorrect, S-2 is correct.
