Why do He and `H_(2` shows exceptional behaviour as compared to rest of the gases ?

Be(IIA) shows different behaviour as compared to other elements of the same group the reason is

Gases like CO_(2) and CH_(4) show more deviation from the ideal gas behaviour as compared to gases like H_(2) and He , Explain

Why is nitrogen anomalous in its behaviour as compared to other members of its group ?

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressure and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas behaviour as compared to the gases which are liquified with difficulty. Gas deviates from ideal gas behaviour because molecules

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressure and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas behaviour as compared to the gases which are liquified with difficulty. The temperature at which the real gases obey the ideal gas laws over a wide range of pressure is called

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressure and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas behaviour as compared to the gases which are liquified with difficulty. The van der Waals equation reduces itself to ideal gas equation at

The deviation are maximum under high pressure and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas behaviour as compared to the gases which are liquified with difficulty. An ideal gas is one which obeys the gas laws under

The deviation are maximum under high pressure and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas behaviour as compared to the gases which are liquified with difficulty. The compressibility factor for an ideal gas is :
