Answer #1

An extremely useful rule of thumb in deciding the solubility of a solute in a solvent is " LIKE DISSOLVES LIKE"

Non-ploar or weakly polar compounds dissolve in nonpolar or weakly polar solvents.

Highly polar compounds dissolve in highly polar solvents

Examples;

Nonpolar solvents : Hydrocarbons ( benzene, toluene, pentane, hexane,cyclohexane etc ), carbon tetra chloride, ether, chloroform etc

Polar Solvents : water, ethanol, methanol, acetone, N,N-Dimethylformamide (DMF), Dimethyl sulfoxide(DMSO), Acetonitrile

Gasoline is a nonploar compound .

Water is a highly polar solvent.

Thumb rule for solubility is " LIKE DISSOLVES LIKE"

Gasoline and Water are not 'like'

So gasoline will not dssolve in water
