Hydrocarbons are non-polar. Water is polar. So from âlike dissolves likeâ you wouldnât expect any of these three to be very soluble in water. In fact, unsaturated and aromatic hydrocarbons are slightly soluble in water- the solubility of toluene in water is ~500mg/L â not very much. Cyclohexene is even less than that.
