Chapter 9, Problem 9.16P

Interpretation Introduction

Interpretation:

An example in which the addition of electrons produces strong bond has to be given.

Concept Introduction:

Bond order

Bond order $\text{=}\frac{\left({\text{N}}_{\text{b}}\right)\text{-}\left({\text{N}}_{\text{a}}\right)}{\text{2}}$

Where, ${\text{N}}_{\text{b}}$ is number of electrons in bonding orbital.

${\text{N}}_{\text{a}}$ is number of electrons in antibonding orbital

Bond order is directly proportional to the bond strength.  Greater the bond order greater is the bond strength.
