Question

The alcohol which easily reacts with conc. HCl is

• A. $CH_{3} - CHOH -CH_{2}-CH_{3}$
• B. $(CH_{3})_{3}-C-OH$
• C. $CH_{3}-CH_{2}-CH_{2}-CH_{2}-OH$
• D. $(CH_{3})_{3}-CH-CH_{2}OH$

Answer 1

Answer: (B)

Tertiary alcohol readily reacts with halogen acid

Presence of 3 alkyl groups increases electron density on $3^{\circ}$ carbon atom. Hence -OH group is easily removed. After the removal of -OH group is easily removed. After the removal of -O H group $3^{\circ}$ carbonium ion is formed which is most stable
