The calcohol which easily reacts with conc. `HCI` is

Options

A. `CH_(3)-CHOH-CH_(2)-CH_(3)`
B. `CH_(3)-CH_(2)-CH_(2)-CH_(2)-OH`
C. `(CH_(3))_(3)-C-OH`
D. `(CH_(3))_(3)-CH-CH_(2)OH`

Answer

C

Explanation

Tertiary alcohol readily reacts with halogen acid
`CH_(3)rarroverset(CH_(3))overset(darr)underset(CH_(3))underset(uarr)C-OHrarrCH_(3)rarroverset(CH_(3))overset(|)underset(CH_(3))underset(|)(C^(+))+OH^(-)`
Presence of `3` alky`1` group increases electron density on `3^(@)` carbon atom. Hence`-OH` group is easily removed. After the removal of `-OH` group `3^(@)` carbonium ion is fromed which is most stable
