Q. The acidic character of $1{^\circ},\ 2{^\circ},\ 3{^\circ}$ alcohols, $H_{2}O$ and $RC \equiv CH$ is of the order
A) $H_{2}O > 1{^\circ} > 2{^\circ} > 3{^\circ} > RC \equiv CH$
B) $RC \equiv CH > 3{^\circ} > 2{^\circ} > 1{^\circ} > H_{2}O$
C) $1{^\circ} > 2{^\circ} > 3{^\circ} > H_{2}O > RC \equiv CH$
D) $3{^\circ} > 2{^\circ} > 1{^\circ} > H_{2}O > RC \equiv CH$
Explanation
(a)
Alcohols are more acidic than alkynes but less acidic than water thus, the correct order of acidity is
$H_{2}O > 1{^\circ} > 2{^\circ} > 3{^\circ} > RC \equiv CH$
