15467 The decreasing order of nucleophilicity among
the following nucleophiles is : $(I)$ $C H_{3} C O O^{Θ}$ $(I I)$ $C H_{3} O^{Θ}$ $(I I I)$ $C H_{3} C H_{2}^{Θ}$ $(I V)$ $C H_{3} S O_{3}^{Θ}$

I I I > I I > I > I V

Explanation:

Nucleophilicity $α \frac{1}{Stability of anion}$
order of stability of anion $\Rightarrow$
