उत्तर
(a) < (b) < (c) < (d)
Explanation:
The density increases with increase in number of carbon atoms, halogen atoms and atomic masses of the halogen atoms bounded with the alkyl or aryl groups. Or, in other words density is related to molecular mass of the compound. Higher the molecular mass, greater will be the density of the compound.
