Answer:
hydrogen chloride (HC)- insoluble in hexane
hydrogen sulfide (H2S)- insoluble in hexane
water (H2O)- insoluble in hexane
propane (CH3CH2CH3)- soluble in hexane
Explanation:
Generally, it is a principle in chemistry that polar solvents dissolve polar substances while nonpolar solvents dissolve nonpolar substances.
This is because, dissolution of a substance in another substance depends on the kind of intermolecular interaction that is possible between the two substances. Hence, ionic substance dissolve in polar solvents due to dipole interactions and nonpolar substances dissolve in nonpolar solvents due to Vanderwaals interaction between the solute and solvent.
Hydrogen chloride, hydrogen sulphide and water are ionic substances hence they can not dissolve in hexane which is a nonpolar substance. However, propane is a nonpolar solvent hence it dissolves in hexane.
Answer: butane (CH3CH2CH2CH3) soluble
hydrogen chloride ( HCl) insoluble
hydrogen sulfide (H_2S) insoluble
water (H_2O) insoluble
