The increasing order of nucleophilicity of the following nucleophiles is :
(a) CH₃CO₂^$-$ (b) H₂O
(c) CH₃SO₃^$-$ (d)

\mathop O\limits^ - H

Accepted Answer

When stability of nucleophile increases then nucleophilicity decreases.

Stability order :
H₂O > CH₃SO₃^$-$ > CH₃CO₂^$-$ >

\mathop O\limits^ - H

So Nucleophilicity order :
H₂O < CH₃SO₃^$-$ < CH₃CO₂^$-$ <

\mathop O\limits^ - H
