Question

Maximum deviation from ideal gas is expected from:- Kindly explain the answer also:-
a) N₂(g)
b) CH₄(g)
c) NH₃(g)
d) H₂(g)

Answer 1

According to Kinetic Theory of gases, very less intermolecular forces are present in the molecules of gas. The maximum intermolecular forces are present in NH₃ due to dipole-dipole attraction. NH₃ molecule is polar in nature and hence behave as a dipole. Therefore, maximum deviation from ideal gas behaviour is shown by NH₃.

Hence the answer is (c).
