Following table represents critical temperature of some gases. Arrange these gases in their increasing order of liquifaction.

Gas	$${H_2}$$	$$He$$	$${N_2}$$	$${O_2}$$
$${T_c}/K$$	33.2	5.3	126	154.3

A. $$He < {N_2} < {H_2} < {O_2}$$

B. $${H_2} < He < {N_2} < {O_2}$$

C. $$He < {H_2} < {N_2} < {O_2}$$

D. $${O_2} < {N_2} < {H_2} < He$$

Answer : $$He < {H_2} < {N_2} < {O_2}$$

Solution :
More will be critical temperature easier is the liquifaction of the gas. Hence correct order will be $$He < {H_2} < {N_2} < {O_2}$$
