IN which of the following pairs, the two species have identical bond order ?

A

`N_(2)^(-) , O_(2)^(2-)`

B

`N_(2)^(-) , O_(2)^(-)`

C

`N_(2)^(-) , O_(2)^(2+)`

D

`O_(2)^(+),N_2^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
C
Total number of electrons in `N_2^(-) =7+7+1=15`
Total number of electrons in `N_(2)^(2-) 7+7+2=16`
Total number of electrons in `O_2^(2-)=8+8+2=18`
Total number of electrons in `O_2^(-)= 8 + 8 + 1 = 17`
Total number of electrons in `O_2^(+) = 8+8 -1 =15`
Configuration will be same if as `N_2^(-) and O_2^(+)` contain the same total number of electrons. Thus `N_2^(-) and O_2^(-)` has the same bond order.
