Sum of bond order of CO and NO ^ + is

Bond order is the number of chemical bonds between a pair of atoms and indicates the stability of a bond. 

Bondorder = \dfrac{Numberofbondingelectrons - numberofantibondingelectrons}{2}$</p><p>The given two molecules have the same number of electrons(14) like nitrogen molecule.</p><p>Hence,$CO ⇒ \overset{¯}{C} ≡ \overset{+}{O}: BO = 3$</p><p>${NO}^{+} ⇒ N ≡ {O}^{+}: BO = 3$</p><p>The sum of the bond order of$CO$and${NO}^{+}$</p><p>$= 3 + 3 = 6
