Answer 1

Question

Chapter 2.SE, Problem 31AP

Interpretation Introduction

a) The H-Cl bond length is 136pm. What would be the dipole moment of H-Cl be if the molecule were 100% ionic, H⁺Cl^-?

Interpretation:

Assuming H-Cl to be 100% ionic its dipole moment is to be calculated. Its bond length is given as 136pm.

Concept introduction:

Dipole moment is defined as, µ=Qxr

Where, Q=Magnitude of the charge developed at either end of the dipole.

R=The distance between the charges

It is expressed in Debyes (D). 1 D=3.336x10^-30C.m

To determine:

The dipole moment of H-Cl assuming it to be 100% ionic. Its bond length is given as 136pm.

Interpretation Introduction

b) The actual dipole moment of H-Cl is 1.08 D. What is the percent ionic character of the H-Cl bond.

Interpretation:

Actual dipole moment of H-Cl is given as 1.08 D. Its percent ionic character is to be calculated.

Concept introduction:

Assuming H-Cl to be 100% ionic and knowing the bond length, the dipole moment of H-Cl can be calculated. From the calculated value and the actual value of dipole moments the percent of ionic character of H-Cl can be determined.

To determine:

The percent ionic character of the H-Cl bond, if its actual dipole moment is 1.08 D.
