Chapter 7.5, Problem 7.5E

(a)

Interpretation Introduction

Interpretation:

Differences in the dipole moments of molecules $\text{HI}\text{and}\text{HBr}$ 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.
