If 1 equivalent NaOH reacts with the given compound: Choose the correct option:

If $\text{1}$ equivalent $\text{NaOH}$ reacts with the given compound:




Choose the correct option: 

1. No reaction occurs.
2. $\mathrm{N}\mathrm{a}\mathrm{O}\mathrm{H}$ reacts with  $\text{-COOH}\left(\text{b}\right)$
3. $\mathrm{N}\mathrm{a}\mathrm{O}\mathrm{H}$ reacts with $\text{-COOH}\left(\text{a}\right)$
4. $\mathrm{N}\mathrm{a}\mathrm{O}\mathrm{H}$ reacts with - $\text{OH}$

Solution

$\text{NaOH}$ is base so it will react with acid.
$\text{H}$ which is attached with $\text{-COOH}$ is more acidic due to the stability of conjugate base (equivalent resonating structure). So, b and c is more basic. And in a and b, b is more acidic because it's conjugate base is stabilised due to $-\text{I}$ effect of ${\text{-NO}}_{\text{2}}$ .
