Options
- A(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
- B(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
- C(A)-(II), (B)-(II), (C)-(III), (D)-(III)
- D(A)-(I), (B)-(I), (C)-(IV), (D)-(IV)
Correct answer
A. (A)-(II), (B)-(I), (C)-(III), (D)-(IV)
Step-by-step solution
(A) Oxidation of p -methoxytoluene with acidic KMnO ₄ yields p -methoxybenzoic acid. The - OCH ₃ group has a strong +M effect which outweighs its -I effect, making the product a weaker acid than benzoic acid. (Matches II) (B) Oxidation of p -chlorotoluene yields p -chlorobenzoic acid. For halogens, the -I effect outweighs the +M effect, making the product a stronger acid than benzoic acid. (Matches I) (C) Reduction of p -nitroanisole with Sn / HCl yields p -anisidine. The +M effect of the - OCH ₃ group increases el
