Question:

The increasing order of nucleophilicity of the following nucleophiles is:

(a) $\mathrm{CH}_{3} \mathrm{CO}_{2}^{\ominus}$

(b) $\mathrm{H}_{2} \mathrm{O}$

(c) $\mathrm{CH}_{3} \mathrm{SO}_{3}^{\ominus}$

(d) $\stackrel{\ominus}{\mathrm{O} H}$

1. (b) $<(\mathrm{c})<(\mathrm{a})<(\mathrm{d})$

2. $(a)<(d)<(c)<(b)$

3. $(d)<(a)<(c)<(b)$

4. $(b)<(c)<(d)<(a)$

Correct Option: 1

Solution:
