Thus there is a weak attraction of the aluminum atoms to the pi electron cloud in the benzene molecule, allowing a small amount of solubility. It is highly soluble in solvents with Lewis base character, such as nitrobenzene or ether.It is poorly soluble in methylene chloride or chloroform.hus there is a weak attraction of the aluminum atoms to the pi electron cloud in the benzene molecule, allowing a small amount of solubility.
