Chapter 10, Problem 10.116QE

Interpretation Introduction

Interpretation:

The molecular orbital diagram of $\text{NO}$ and $\text{CO}$ has to be given and species that has lower ionization energy has to be predicted.

Concept Introduction:

Ionization energy:

Ionization energy is the energy required to remove an electron from a gaseous atom or atom.  The first or initial ionization energy or ${\text{E}}_{\text{1}}$ of an atom or molecule is the energy required to remove one mole of electrons from one mole of isolated gaseous atoms or ions.

Bond order of a molecule or ion is calculates by the following formula,

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.
