Question

What is the bond order of B\(_2\) molecule?

• A. 0
• B. 1
• C. 3
• D. 2

Hint:

For molecules with an even number of electrons in their molecular orbitals, bond order can sometimes be zero, indicating no stable bond.

Answer 1

The Correct Option is A

Step 1: Understanding bond order.
Bond order can be determined using molecular orbital theory. For the B\(_2\) molecule, the molecular orbitals are filled as follows: - The bonding electrons in \(\sigma_{2s}\) and \(\sigma^*_{2s}\) cancel out, leaving a bond order of 0.

Step 2: Conclusion.
The bond order of B\(_2\) is 0, meaning there is no bond between the two boron atoms.
