Question

The alcohol which easily reacts with conc. HCl is

• A. $C{H}_3-CHOH-C{H}_2-C{H}_3$
• B. $(C{H}_3{)}_3-C-OH$
• C. $C{H}_3-C{H}_2-C{H}_2-C{H}_2-OH$
• D. $(C{H}_3{)}_3-CH-C{H}_{2}OH$

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
