One reason ionic compounds do not dissolve well in nonpolar solvents is that
a. ion-solvent interactions are not strong enough to solvate the ions in solution.
b. not all cations and anions have the same magnitude of charge and therefore do not form neutral ion pairs.
c. ion-dipole interactions are too large for effective solvation to occur. d. there are no forces of attraction between ions and nonpolar molecules.

d. there are no forces of attraction between ions and nonpolar molecules.

Explanation:

Solubility is determined by the principle , "like dissolves like" .

i.e. , if a compound is polar then it will dissolve in a polar compound only , and

if a compound is non - polar then it will dissolve in a non - polar compound only .

Ionic compound , are polar in nature , i.e. , have a positive and negative charge , polar solution can only dissolve in polar ,

As ,  there will be interaction between the opposite charge , and hence will dissolve .

And , in case of a polar and non polar solution , there won't be any interaction , and hence will not dissolve .

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

the answer is 75.0%.
