Solution

The correct option is E There are intermolecular attractive forces
Some of the non-ideal behavior observed in real gases can be best accounted by the fact that there are intermolecular attractive forces.
In case of ideal gases, it is assumed that no intermolecular forces are present.

Q. Real gases show deviations from ideal gas law because molecules interact with each other. At high pressures molecules of gases are very close to each other. At very low temperatures intermolecular forces become significant. The deviation from ideal gas behaviour can be measured in terms of compressibility factor
