Deviation from ideal gas law

You might need: Periodic table

The following graph shows the relationship between temperature and pressure for

1.0 mol

samples of

C_{2} H_{6} (g)

and

N_{2} (g)

confined in separate

1.0 L

containers. Ideal behavior under these conditions is indicated by a dashed line.

Which of the following best explains why the $C_{2} H_{6} (g)$ ‍ sample deviates more from ideal behavior at $300 K$ ‍ than the $N_{2} (g)$ ‍ sample does?

(Choice A)
$C_{2} H_{6}$ ‍ molecules form hydrogen bonds, whereas $N_{2}$ ‍ molecules do not.
(Choice B)
$C_{2} H_{6}$ ‍ molecules interact through stronger dispersion forces than $N_{2}$ ‍ molecules do.
(Choice C)
$C_{2} H_{6}$ ‍ molecules have a larger volume than $N_{2}$ ‍ molecules do.
(Choice D)
$C_{2} H_{6}$ ‍ molecules have a higher average speed at $300 K$ ‍ than $N_{2}$ ‍ molecules do.
