Given below are two statements.

Statement I : The compound A is optically active.

Statement II : B is mirror image of above compound A.
In the light of the above statement, choose the most appropriate answer from the options given below.
Structure A
A
Structure B
B
  1. (A)Both Statement I and Statement II are correct
  2. (B)Both Statement I and Statement II are incorrect.
  3. (C)Statement I is correct but Statement II is incorrect.✓ Correct
  4. (D)Statement I is incorrect but Statement II is correct.

Answer: (C)

Solution

Compound A contains a chiral center (the carbon bearing the nitro group has four different substituents), making it optically active. Statement I is correct. However, compound B shown has the same configuration at the chiral center as compound A (not the opposite configuration), so B is NOT the mirror image of A; they are the same compound. Statement II is incorrect. Therefore, Statement I is correct but Statement II is incorrect.
