Question

Mark the correct order of decreasing acid strength of the following compouns.

A

(v) > (iv) > (ii) > (i) > (iii)

B

(ii) > (iv) > (i) > (iii) > (v)

C

(iv) > (v) > (iii) > (ii) > (i)

D

(v) > (iv) > (iii) > (ii) > (i)

Answer

(ii) > (iv) > (i) > (iii) > (v)

Explanation

Solution

The electron withdrawing group $( - NO_{2})$ increases the acidity of phenols and the electron donating group $( - OCH_{3})$ decreases the acidity of phenols. The effect at p-position is greater than at m-position.
