Chapter 12, Problem 64E

Interpretation Introduction

Interpretation:

In each of the given compounds, determine the kind of intermolecular forces existing between their molecules.

Concept introduction:

The attractive forces existing between molecules are said to be intermolecular forces. These forces are the result of mainly three types of interactions:

(a) Dipole–dipole interactions

(b) Dipole–induced dipole interactions

(c) Induced dipole–induced dipole interactions

There are four types of intermolecular forces:

(a) Dispersion forces: These are the intermolecular forces present in all the molecules and atoms by virtue of the electrons present in them.

(b) Dipole–dipole interactions: These are the forces that exist in all polar molecules. They have permanent dipole in which positive end of one permanent dipole is attracted to the negative end of other.

(c) Hydrogen bonding: These forces exist in those molecules having hydrogen atoms bonded directly to the electronegative elements like fluorine, oxygen, or nitrogen.

(d) Ion–dipole forces: Such types of forces exist between the ionic compound molecules.
