N2 and O2 are converted into monoanions ...

`N_2` and `O_2` are converted into monoanions `N_2^-` and `O_2^-` respectively. Which of the following statements in wrong ?

A

In `N_2`, then N - N bond weakens

B

In `O_2`, the O - O bond order decreases

C

In `O_2`, bond length increases

D

`N_2^(-)` becomes diamagnetic

Text Solution

Verified by Experts

The correct Answer is:
D
Correct sequence of B.O. in increasing order is
`underset((B.O. = 2)(B.O. = 1.5))(O_2 gt O_2^(-))`
`underset((B.O. = 3)(B.O. = 2.5))(N_2 gt N_2^(-))`
Since B.O. is fractional so cannot be diamagnetic order of bond length is `O_2^(-) gt O_2`.
