Four diatomic species are listed below. Identify the correct order in which the bond order is increasing in them:
- NO < O2 < C2− < He2+
- O2 < NO < C2− < He2+
- C2− < He2+ < O2 < NO
- He2+ < O2 < NO < C2−
Correct answer: O2 < NO < C2− < He2+
Solution
The bond order increases in the order O2 < NO < C2− < He2+.
