Explanation:

Strength of intermolecular forces depends on the number of carbon atoms present in a compound. More is the number of carbon atoms attached linearly to each other more will be the surface area occupied by it. Hence, more is the strength of the compound.

This means that more is the branching present in a compound or lesser is the number of carbon atoms present in it then less will be the strength of intermolecular forces in the compound.

Thus, we can conclude that given compounds are placed in order of decreasing strength of intermolecular forces as follows.

$CH_3CH_2CH_2CH_2CH_2CH_3$ > $(CH_3)_3CCH_2CH_3$ > $(CH_3)_3CCH_3$
