jee-98 q

in HNO₃, there is resonance... so we can say that it has two partial double bonds connecting N and O...
whereas in HNO₂, there is only one..

thus statement 2 is correct..

but N to O bonds are 3 in hno3, aren't they?..why did u count only double bonds?

in HNO₃,
THERE ARE 2 nitrogen to oxygen bond (bonded directly.)
the other one is a N-OH bond not a N-O bond.

2 is incorrect

N-OH me N-O bond nahi hai kya LOL

obviously st-1 is correct and st-2 is false. there are 3 N-O bonds in HNO₃ . some day pour HNO₃ and HNO₂ on yr different hands. u would get the feeling within a moment. the K_a value of HNO₃ is very high- about 10³.

and this question was an assertion reasoning one.
