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:
Structure Compound A
Compound A
Structure Compound B
Compound B
  1. (A)Both Statement I and Statement II are correct
  2. (B)Statement I is incorrect but Statement II is correct✓ Correct
  3. (C)Statement I is correct but Statement II is incorrect
  4. (D)Both Statement I and Statement II are incorrect

Answer: (B)

Solution

Statement I: numbering for lowest locants makes Compound A 1-chloro-2,4-dinitrobenzene, not "4-chloro-1,3-dinitrobenzene" — so Statement I is incorrect. Statement II: the amine is correctly named 4-ethyl-2-methylaniline — correct. Hence I incorrect, II correct. Option (2).
