Solution

The correct options are
A Critical temperature < Boyle's temperature
B van der Waal's constant 'a' : $H_{2} O > N H_{3} > N_{2} > N e$
C Heat capacity: $N H_{3} > C O_{2} > O_{2} = N_{2} > A r$
D Mean free path: $H e > H_{2} > O_{2} > N_{2} > C O_{2}$
As we know,
$C_{v} = R / γ - 1$
so as atomcity of gas increases, heat capacity increases.
so order is
Heat capacity: $N H_{3} > C O_{2} > O_{2} = N_{2} > A r$
Also as atomcity and mass increases, mean path decreases so order is
Mean free path: $H e > H_{2} > O_{2} > N_{2} > C O_{2}$
The 'a' values for a given gas are measure of intermolecular forces of attraction. More are the intermolecular forces of attraction, more will be the value of a.
so order is
van der Waal's constant 'a' : $H_{2} O > N H_{3} > N_{2} > N e$
