Chapter 2, Problem 4PP

Interpretation Introduction

Interpretation:

The fact that tetrachloroethene $\left({\text{CCl}}_{\text{2}}={\text{CCl}}_{\text{2}}\right)$ does not have dipole moment is to be explained on the basis of the shape of tetrachloroethene $\left({\text{CCl}}_{\text{2}}={\text{CCl}}_{\text{2}}\right)$.

Concept Introduction:

If the molecule has dipole moment, it is termed as polar molecule. The symmetrical molecules are non-polar because the dipole moment vectors cancel each other.

In non-polar covalent bonds, electrons are shared equally between the atoms.
