Maximum oxidation number

Vedclass · Answer

(B) The correct option is $B$.In $HNO_2$,the oxidation number of $N$ is $+3$. Since the maximum oxidation state of $N$ is $+5$,it can be oxidized to $+5$ (acting as a reductant) or reduced to a lower state (acting as an oxidant).In $HNO_3$,the oxidation number of $N$ is $+5$,which is the maximum possible oxidation state for nitrogen. Therefore,it can only be reduced,acting exclusively as an oxidant.

$HNO_2$ acts both as a reductant and an oxidant,while $HNO_3$ acts only as an oxidant. This is due to their:
