Which of the following statement would be INCORRECT about this compound ?

Answer»

All THREE C-N bond are of same length
`C_1 -N and C_3-N` bonds are of same length but shorter than `C_5-N` bond
`C_1 -N and C_5-N` bonds are of same length but longer than `C_3-N` bond
`C_1 -N and C_5-N` bonds are of same length but both longer than `C_3-N` bond

SOLUTION :Due to steric HINDERANCE of three groups `-NO_2` GROUP go out of the plane with benzene ring and so conjugation of `-NO_2` group with benzene is slightly diminished.So bond length of `C_1-N` & `C_5-N` is more than `C_3-N`
