Indicate whether each statement is true or false. Sort these statements into the proper categories.

A) NaCl dissolves in water but not in benzene (C6zH6) because benzene is denser than water.

B) NaCl dissolves in water but not in benzene because water has a large dipole moment and benzene has zero dipole moment.

C) NaCl dissolves in water but not in benzene because the water-ion interactions are stronger than benzene-ion interactions.

B - true

C - false

In chemistry there is a principle that polar compounds are soluble with other polar compounds and non-polar compounds are mutually different.

Thus, sodium chloride is an ionic salt (polar) so it is not soluble in the benzene (non-polar) covalent compound, but it is soluble in water that is polar.

The ionic compounds will be soluble in polar solvents and not soluble in non-polar solvents, regardless of whether they are organic or inorganic.
