Which of the following molecules do you expect to have the highest boiling point?

NH 3 Ne  O 2 NO

Interpretation Introduction

Interpretation:

The given molecule having the highest boiling point as compared to others is to be determined.

Concept Introduction:

The boiling point of a molecule depends upon intermolecular forces and thermal energy.

Intermolecular forces keep molecules together. Greater the intermolecular force, greater will be the boiling point.

Intermolecular forces are of two types: dispersion forces and dipole forces.

Dispersion forces are possessed by all atoms or molecules. It depends upon molar mass.

Dipole forces exist between polar molecules. It depends upon the polarity of the molecules.

The boiling point also increases because of intermolecular hydrogen bonding.

Explanation of Solution

The boiling point of a molecule depends upon intermolecular forces and thermal energy. Intermolecular forces depend upon dispersion forces, which in turn depend upon molar mass. The boiling point also increases because of intermolecular hydrogen bonding.

Higher the molar mass, higher will be the magnitude of its dispersion forces and hence, higher will be the boiling point. NH3 has the highest molecu
