Chapter 9, Problem 137RQ

Interpretation Introduction

Interpretation:

The chemical formula of the phosphorus-bromine compound based on the information given and whether it is polar or nonpolar, is to be determined.

Concept Introduction:

When atoms in a molecule show difference in their electronegativities, it results in acquiring of the partial ionic charge (negative or positive charge) on the individual atom which occurs because of the partial transfer of electron density from one atom to another.

Such situations create a polarity between the two atoms. The greater the difference between the electronegativities, the stronger is the ionic bond and hence, the higher the polarity.

The number of moles of a molecule can be determined by dividing the mass of a molecule by the molar mass of the molecule and is represented by, $\text{n=}\frac{\text{m}}{\text{M}}$.
