The alcohol which easily reacts with conc. HCl is

A

CH3−CHOH−CH2−CH3CH_{3} - CHOH - CH_{2} - CH_{3}

B

(CH3)3−C−OH(CH_{3})_{3} - C - OH

C

CH3−CH2−CH2−CH2−OHCH_{3} - CH_{2} - CH_{2} - CH_{2} - OH

D

(CH3)3−CH−CH2OH(CH_{3})_{3} - CH - CH_{2}OH

Answer

(CH3)3−C−OH(CH_{3})_{3} - C - OH

Explanation

Solution

Tertiary alcohol readily reacts with halogen acid

C2H5OHC_{2}H_{5}OH

Presence of 3 alkyl group increases electron density on H2SO4H_{2}SO_{4}carbon atom. Hence C2H5OHC_{2}H_{5}OH group is easily removed. After the removal of H2SO4H_{2}SO_{4} group H2SO4,H_{2}SO_{4}, carbonium ion is formed which is most stable
