Name three oxoacids of nitrogen. Write the disproportionation reaction of that oxoacid of nitrogen is in +3 oxidation state.

Explanation

Three oxoacids of nitrogen having oxidation state + 3 are
(a) `HNO_(2)`, nitrous acid
(b) `HNO_(3)` nitric acid
( c) Hyponitrous acid , `H_(2)N_(2)O_(2)`
In `HNO_(2)` N is + 3 oxidation state
Disproportionation reaction
`3HNO_(2)overset("Disproportionation")toHNO_(3)+H_(2)O+2NO`
