Question

Why is benzene is unsoluble in water but soluble in toluene ?

Answer 1

Answer:

because the role of density

Explanation:

benzene density is much higher than the water so it will float not mix

but in case of toluene density is not higher than benzene therfore it is soluble

Answer 2

Answer:

Benzene is non-polar, therefore it is insoluble in water(polar solvent) . Whereas it is soluble in Toulene which is non-polar solvent i. e non polar compounds are soluble in non - polar solvents and polar compounds are soluble in polar solvents.

In short just remember that "like dissolves like"
