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

Options

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

B

Explanation

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