Question

Structure of nitric acid in gaseous state is represented as. Pick the incorrect statement and/or order for it

1) it can not be prepared by hydrolysis of NCl₃

2) it is a planar molecule

3) order of bond angles is a > b > y

4) order of bond length x > y > 

Answer 1

In the gaseous state, HNO₃ exists as a panes molecule from above figure:----

α > β > γ

γ > x > Ƶ

NCl₃ + 3H₂O → NH₃ + \(\underset{Hypochlorous\,acid}{3HOCl}\) 

therefore, Option (i) and (iv) is incorrect statement.

Hence, Option (i) and (iv) is Right answer.
