Chemistry Question on p -Block Elements

The correct order of nucleophilicity is

A

FF^– > OHOH^–

B

H2OH_2O > OHOH^-

C

ROHROH > RORO^-

D

NH2\text{NH}_2^{-} > NH3NH_3

Answer

NH2\text{NH}_2^{-} > NH3NH_3

Explanation

Solution

The correct answer is (D) : NH2\text{NH}_2^{-} >NH3> NH_3
NH3NH_3 NH2\text{NH}_2^{-} + H+H^+
Acid Conjugate base
Conjugate base of acid is always a stronger nucleophile.
