Stability of a crystal is reflected in the magnitude of its melting point'. Comment. Collect melting points of solid water, ethyl alcohol, diethyl ether and methane from a data book. What can you say about the intermolecular forces between these molecules?

ANSWER:-

Melting points of substances

Water = 273K

Ethyl alcohol = 155•7K

Diethyl ether = 156•8K

Methane = 90•5K.

The stability of crystals depends up on the packing of the atoms. if there are strong force of attraction between the constituent particles then greater the stability.

Water – strong intermolecular hydrogen bonding

Ethyl alcohol – strong intermolecular hydrogen bonding.

Diethyl ether – it is a polar molecule so there is dipole –dipole attraction

Methane – is a non–polar molecule so that there is weak van der Waal's forces (London dispersion forces).
