The species having bond order different ...

The species having bond order different from that in `CO` is

A

`NO^(-)`

B

`NO^(+)`

C

`CN^(-)`

D

`N_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`NO^(+), CN^(-) and N_(2)` are isoelectronic with CO
(containing 14 electrons each) . Hence , all of tham
have the same bond order , viz ., `3 NO^(-)` has 16
elelctrons with the same configuration as that `O_(2)`
Hence , its bond order = 2
