Chapter 7, Problem 45QRT

(a)

Interpretation Introduction

Interpretation:

Differences in the dipole moments of molecules $\text{BrF}\text{and}\text{BrCl}$ have to be explained.

Concept Introduction:

The unequal distribution of shared electrons caused by differences in electronegativity between bonded atoms is called bond polarity.

Dipole moment: It is the measure of the charge separation that is describes the polar in the bond between the two atoms.

Electronegativity: It is defined as the capacity of the atom to abstract the pair of electrons towards itself results to have high negative charge.

(b)

Interpretation Introduction

Interpretation:

Differences in the dipole moments of molecules ${\text{H}}_{\text{2}}\text{O}$ and ${\text{H}}_{\text{2}}\text{S}$ have to be explained.
