Chapter 5, Problem 5.54SP

Interpretation Introduction

Interpretation:

From the given molecular orbital diagram, which of the three is likely to be stable, the bond order of the each and which contain unpaired electrons has to be determined.

Concept introduction:

Bond order:

• Bond order is nothing but the number of chemical bonds that involved in between a pair of atoms.
• Bond order indicates the stability of a bond and it reflects the stability of the molecule.
• An element having bond order zero value is not exit in the universe, but compounds may have a bond order of zero.
• According to molecular orbital theory bond order can be calculated by using the following formula.

$\text{B}\text{.O =}\frac{\text{number of bonding electrons - number of antibonding electrons}}{\text{2}}$
