For hydrazoic acid, which of the following resonating structure well be least stable?
`underset("(I)")(H-N=overset(+)N=overset(-)N)harrunderset(" (II)")(H-overset(+)N-overset(+)N=N^(2-))harrunderset("(III)")(H-overset(-)N-overset(+)N-=N)`

A

I

B

II

C

III

D

Both (I) and (III)

Text Solution

Verified by Experts

The correct Answer is:
B
(II) is least stable because of like charges on adjacent atoms.
