NTA AbhyasNTA Abhyas 2020 Report Error

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

$\left(\right.CH_{3}\left(\left.\right)_{3}-CH-CH_{2}OH$

Solution:

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.
