Question: The correct sequence of decreasing acidity is...

The correct sequence of decreasing acidity is

A

(CH3)3COH>(CH3)2CHOH>C2H5OH>CH3OH(CH_{3})_{3}COH > (CH_{3})_{2}CHOH > C_{2}H_{5}OH > CH_{3}OH

B

CH3OH>C2H5OH>(CH3)3COH>(CH3)3COHCH_{3}OH > C_{2}H_{5}OH > (CH_{3})_{3}COH > (CH_{3})_{3}COH

C

C2H5OH>CH3OH>(CH3)3COH>(CH3)2CHOHC_{2}H_{5}OH > CH_{3}OH > (CH_{3})_{3}COH > (CH_{3})_{2}CHOH

D

(CH3)2CHOH>(CH3)3COH>C2H5OH>CH3OH(CH_{3})_{2}CHOH > (CH_{3})_{3}COH > C_{2}H_{5}OH > CH_{3}OH

Answer

CH3OH>C2H5OH>(CH3)3COH>(CH3)3COHCH_{3}OH > C_{2}H_{5}OH > (CH_{3})_{3}COH > (CH_{3})_{3}COH

Explanation

Solution

Presence of electron releasing group decreases the acidity of the alcohols hence t<s<p

Hence

CH3OH>C2H5OH>(CH3)2CHOH>(CH3)3COHCH_{3}OH > C_{2}H_{5}OH > (CH_{3})_{2}CHOH > (CH_{3})_{3}COH
