Chapter 4, Problem 77AP

Interpretation Introduction

Interpretation: Whether $\text{ICl}$ molecule is ionic, polar covalent or nonpolar covalent should be determined.

Concept Introduction:

Ionic, polar covalent and nonpolar covalent molecules can be very easily distinguished by calculation the electronegativity difference between the constituting atoms of the molecules.

1. For electronegativity difference less than 0.5, the atoms form non-polar covalent bonds.
2. For electronegativity difference between 0.5 and 2, the atoms form polar covalent bonds.
3. For electronegativity difference more than 2, the atoms form ionic bonds.
