Following table represents critical temperature of some gases. Arrange these gases in their increasing order of liquefaction.
Gas - H2 - He - N2 - O2
Tc/K - 33.2 - 5.3 - 126 - 154.3
(a) He < N2 < H2 < O2
(b) H2 < He < N2 < O2
(c) He < H2 < N2 < O2
(d) O2 < N2 < H2 < He

Correct answer: (c) He < H2 < N2 < O2
Explanation:
More will be critical temperature easier is the liquefaction of the gas. Hence correct order will be He < H2 < N2 < O2
