Question

The decreasing order of nucleophilicity among the nucleophiles : (A) $CH_{3}\underset{\underset{O}{||}}{C}-O^-$ (B) $CH_3O^-$ (C) $CN^-$

A

$(C), (B), (A), (D)$

B

$(B), (C), (A), (D)$

C

$(D), (C), (B), (A)$

D

$(A), (B), (C), (D)$

Answer

$(C), (B), (A), (D)$

Explanation

Solution

If acid is weak, its conjugate base (nucleophile) is strong and vice versa. Acidic nature of IV > I > III > II and nucleophilicity of B > C > A > D
