Suggest why sodium chloride, NaCl, is insoluble in gasoline. Consider the electrical attractions.
A. Since this molecule is so small, there is not much opportunity for the gasoline to interact with it through any electrical attractions.
B. Since gasoline is a very polar molecule, the salt can only form dipole-induced dipole bonds, which are very weak, giving it a low solubility in gasoline.
C. Salt is composed of ions that are too attracted to themselves. Gasoline is nonpolar, so salt and gasoline will not interact very well.
D. Since gasoline is so strongly attracted to itself, the salt, NaCl is excluded.
