Question

The bond order of which of the following two species is the same?

• A. \( O_2, N_2 \)
• B. \( C_2, O_2 \)
• C. \( B_2, C_2 \)
• D. \( F_2, C_2 \)

Hint:

Bond order indicates the stability of a molecule. A higher bond order means a stronger and shorter bond.

Answer 1

The Correct Option is B

Step 1: Use the Bond Order Formula Bond order is given by: \[ \text{Bond order} = \frac{\text{Number of bonding electrons} - \text{Number of antibonding electrons}}{2} \] 
Step 2: Compute Bond Orders \( C_2 \): Electronic configuration in molecular orbitals gives bond order = 2. \( O_2 \): Electronic configuration in molecular orbitals also gives bond order = 2. Since both species have the same bond order, they are the correct answer.
