According to MO theory, number of species/ions from the following having identical bond order is____ CN - , NO + , O 2 , O 2 + , O 2 2 +

Step-by-step solution

The bond order of a diatomic species can be calculated using molecular orbital theory as follows, Bond   order = No . of   BMO   electrons - No . of   ABMO   electrons 2 BMO = bonding molecular orbital ABMO = Anti bonding molecular orbital. Based on the total number electrons in bond orders are given in the following table. Number of e - Bond order 13 2 . 5 14 3 15 2 . 5 16 2 CN -   ,   NO +   and   O 2 2 + are having 14 electrons each, hence the bond order is 3.
