Assertion :- Bond order of `O_(2)` and BN is same .
Reason `O_(2) and BN` are isoelectronic

The bond order of O_(2)^(-) is

The bond order in O_(2)^(-) ion is

The bond order in O_(2)^(+) is same as in

The bond order in O_2^+ is the same as in :

Assertion : Bond order for CO is more than bond order in CO whereas bond order in N_(2)^(-) is less than N_(2) whereas both are isoelectronic. Reason : Both are same bond order.
