Interpretation Introduction

Interpretation:

The intermolecular forces responsible for the solubility of radon gas in water should be explained.

Concept introduction:

• Intermolecular forces:

Intermolecular forces are the forces that act between one molecule to other molecules as an attraction. These are mainly three types:

1. Dipole-dipole interaction
2. Hydrogen bond
3. London dispersion force.

• London dispersion force:

1. London dispersion force is an intermolecular force which occurs between atoms or molecules which are polar or non-polar and another atom or molecule which are polar or non-polar.
2. It occurs between all molecules or atom.
3. London dispersion forces are the result of temporary dipoles in the atoms or molecules.

• Dipole-dipole interaction:

1. This type of interaction forces is found between polar molecules.
2. The strength of this force is increasing with increasing polarity of molecules.

• Hydrogen bond:

1. Generally, a hydrogen bond is found in those molecules which have covalently hydrogen atom bonded with high electronegative atoms like oxygen, nitrogen, and fluorine.
2. Hydrogen bond found in polar molecules containing unpaired electrons along with a hydrogen atom bonded with oxygen, nitrogen or fluorine atom.
