* Benzene is non-polar: This means its electrons are distributed evenly, creating no distinct positive or negative ends.
* Water is polar: It has a positive end (near the hydrogen atoms) and a negative end (near the oxygen atom).
The Rule: "Like dissolves like." Polar solvents dissolve polar solutes, and non-polar solvents dissolve non-polar solutes.
Therefore: Benzene, being non-polar, will not dissolve well in water.
The BEST answer: Benzene will not dissolve well in water because it is non-polar and water is polar.
