Question

Which one of the following has only a conjugate acid but no conjugate base :

Easy

A

$H_{2} {PO}_{2}^{-}$
B

${OH}^{-}$
C

${HSO}_{4}^{-}$
D

${NH}_{3}$

Solution

$H_{3} {PO}_{2}$ is monoprotic (or) monobasic
$∴ H_{2} {PO}_{2}^{-}$ cannot lose a proton
Thus conjugate acid of $H_{2} {PO}_{2}^{-} is H_{3} {PO}_{2}^{} but H_{2} {PO}_{2}^{-}$ cannot have conjugate base;
