Chapter 2, Problem 3PP

Interpretation Introduction

Interpretation:

The observation that boron trifluoride $\left({\text{BF}}_{\text{3}}\right)$ having no dipole moment confirms the geometry of ${\text{BF}}_{\text{3}}$ predicted by the VSPER theory is to be explained.

Concept introduction:

If a molecule has a dipole moment, it is termed as a polar molecule. Symmetrical molecules are nonpolar because the dipole moment vectors cancel each other.

In nonpolar bonds, electrons are shared equally among the atoms.
