Which of the following show maximum bond-order?
Options
- AO 2
- BO 2 -
- CO 2 +
- DO 2 2 -
Correct answer
C. O 2 +
Step-by-step solution
∵ Bond order BO = N b - N a 2 Here, N b and N a are the number of bonding and anti bonding electrons, respectively. for O 2 , BO = 10 - 6 2 = 2 for O 2 - , BO = 10 - 7 2 = 1 . 5 for O 2 + , BO = 10 - 5 2 = 2 . 5 for O 2 2 - , BO = 10 - 8 2 = 1 Hence, maximum value for BO is for O 2 + .
