Explanation / Answer

Naphthalene does not contain an oxygen atom and is a nonpolar compound. Thus, C10H8is insolublein water.

DDT is insoluble in water, it is difficult to wash away in the environment.On the other hand, DDT is soluble in lipids (fats).

alanine is soluble in water (but not in alcohol).

benzopyrene is partially insoluble in water.but soluble in benzene.

Paradichlorobenzene is almost insoluble in water
