Question

Which alcohol can react easily with $conc.HCl$ ?

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

Answer 1

Answer: (B)

Tertiary alcohol readily reacts with halogen acid.

The presence of 3 alkyl groups increases electron density on
removal of $-OH$ group. A $3^\circ $ carbonium ion is formed which is most stable.
