Chapter 4, Problem 51CTQ

Interpretation Introduction

Interpretation: Reason for no dipole moment arrows for $\text{C}-\text{H}$ bond in the below molecule should be determined.

  

Concept introduction: Dipole moment is measure of bond polarity in molecule. It is defined as product of charge and distance of separation between opposite charges. Since dipole moment is result of charge separation, electronegativity difference plays significant role to govern dipole moment in molecules. Dipole moment exists for molecules that have significant amount of electronegativity difference between bonded atoms.
