Homework Answers
Regarding the solubility of all the given mixtures i.e., hexane and cyclohexene, hexane and toluene and cyclohexene and toluene, they are all soluble. This is because all of them arenon-polar compounds. As we all know, like dissolves in like i.e., non polar dissolves in non-polar and polar dissolves in polar. Thus all the given combinations are soluble.
Thus the general statement is that hydrocarbons are soluble in other hydrocarbons while they are insoluble in water. (as water is polar and hydrocarbons are non polar)
