Chapter 12, Problem 6QAP

Interpretation Introduction

Interpretation:

The comparison between the bonding found in ${\text{H}}_{\text{2}}\left(\text{g}\right)$ and $\text{HF}\left(\text{g}\right)$ molecules with that found in $\text{NaF}\left(\text{s}\right)$ is to be stated.

Concept Introduction:

The tendency of an atom to attract electrons towards it is referred to as electronegativity. It aids in the unequal distribution of charges in a molecule. The electronegativity is the primary factor that determines the type of bond formed. The general rule is that if the electronegativity difference is more than $2$, then the bond formed will be ionic. The polar covalent bond will be formed if the electronegativity difference is between $0.5$ to $2$.

There are two types of polar bonds named as polar covalent bonds and non-polar covalent bonds.
