# NEET Chemistry The p-Block Elements (XII) Questions Solved

Assertion : $HN{O}_{3}$  is stronger acid than $HN{O}_{2}$.

Reason : In $HN{O}_{3}$ there are two nitrogen to oxygen bonds where as in $HN{O}_{2}$ there is only one.

(C)Conjugate base of $HN{O}_{3}$, the $N{O}_{3}^{-}$ is more stable (charge dispersion on three oxygen atoms) than conjugate base of $HN{O}_{2}$, the $N{O}_{2}^{-}$ (charge dispersion on two oxygen atoms).

There are three nitrogen to oxygen bonds in $HN{O}_{3}$ and two in $HN{O}_{2}.$
