Chapter 10, Problem 10A.3E

Interpretation Introduction

Interpretation:

The magnitude and direction of dipole moment in carbon monoxide has to be calculated and it has to be compared with the observed dipole moment and reason should be given.

Concept introduction:

Polar molecules are the molecules having a positive and negative end and so there will be a charge separation.

A polar molecule is a molecule where the polar bonds are asymmetrically arranged (the dipoles do not cancel)

A nonpolar molecule is a molecule with no polar bonds or a molecule where the polar bonds are symmetrically arranged.

In polar molecule the charge separation occurred with respect to the difference in electronegativity of atoms in the molecule.

Direction of dipole moment in a molecule is can be represented as follows,

Calculation of the dipole moment of polyatomic molecules:

$\text{μ}\text{=}{\left({\text{μ}}^{\text{2}}{}_{\text{1}}\text{+}{\text{μ}}^{\text{2}}{}_{\text{2}}\text{+}{\text{2μ}}^{\text{2}}{}_{\text{1}}{\text{μ}}^{\text{2}}{}_{\text{2}}\text{cosθ}\right)}^{\raisebox{1ex}{$\text{1}$}\!\left/ \!\raisebox{-1ex}{$\text{2}$}\right.}$
