Option (5) is the correct answer.

Explanation:

It is known that more is the number of carbon atoms linearly present in a compound more will be its boiling point. This is because then more number of intermolecular forces are present within the atoms of a compound.

Hence, lesser is the number of carbon atoms present less will be the intermolecular forces present in it. Therefore, more readily the compound will evaporate into the atmosphere.

Thus, we can conclude that given compounds are ranked in increasing rate of evaporation as follows.
