Chemistry Question on Alcohols, Phenols and Ethers

Arrange the following compounds in the increasing order of their acidic strength i. mm-nitrophenol ii. mm-cresol iii. phenol iv. mm-chlorophenol

A

iii<ii<i<iviii < ii < i < iv

B

ii<iv<iii<iii < iv < iii < i

C

ii<iii<iv<iii < iii < iv < i

D

ii<iii<i<ivii < iii < i < iv

Answer

ii<iii<iv<iii < iii < iv < i

Explanation

Solution

undefined m-cresol has an electron releasing group (CH). Hence, it decreases the acidic strength .Both nitro and chloro are having -I-effect. Hence, they show higher acidic strength. But nitro is a stronger -I-group than chloro group. Hence, m-nitro phenol is more acidic than m-chlorophenol. So increasing order of acidic strength is II < III < IV < I.
