Identify the bond order of NO ⁺ ion.
Options
- A1
- B2
- C3
- D4
Correct answer
A. 1
Step-by-step solution
The NO ⁺ ion contains 14 electrons, with 7 from nitrogen and 8 from oxygen minus 1 due to the positive charge. Its molecular orbital configuration follows the standard filling order for diatomic molecules: ( 1s)^2 ( ^* 1s)^2 ( 2s)^2 ( ^* 2s)^2 ( 2p)^4 ( 2p)^2 . The bond order is calculated as half the difference between bonding and antibonding electrons. There are 10 bonding electrons ( 1s , 2s , 2p , and 2p ) and 4 antibonding electrons ( ^* 1s and ^* 2s ), giving 1 2 (10 - 4) = 3 . The bond order is 3 , correspon
