Question

The correct pair(s) of the ambident nucleophiles is (are):

$\left(A\right)AgCN/KCN$

$\left(B\right)RCOOAg/RCOOK$

$\left(C\right)AgN{O}_2/KN{O}_2$

$\left(D\right)AgI/KI$

• A. (A) and (C) only
• B. (B) only
• C. (B) and (C) only
• D. (A) only

Answer 1

The correct option is A (A) and (C) only

Answer: (a)More than one electron-donating side.

Cyanide $C{N}^{-}$ and $N{O}_2^{-}$ ions are ambident nucleophiles and can cause nucleophilic substitution of alkyl halide by either of their atoms.
In cyanide substitution can occur through carbon atom or nitrogen atom. In nitrite ion substitution of alkyl halide can occur through by either of its oxygen atoms or nitrogen atom.
