Sum of bond order of CO and NO + is

Correct answer

6

Step-by-step solution

Bond order is the number of chemical bonds between a pair of atoms and indicates the stability of a bond. Bond order = Number of bonding electrons - number of antibonding electrons 2 The given two molecules have the same number of electrons(14) like nitrogen molecule. Hence, CO ⇒ C ¯ ≡ O + : BO = 3 NO + ⇒ N ≡ O + : BO = 3 The sum of the bond order of CO and NO + = 3 + 3 = 6
