Question

Quizplus · Accepted Answer

Polar protic solvents have hydrogen atoms attached to electronegative atoms like oxygen or nitrogen which can form hydrogen bonds with solutes. Ethanol and water have such hydrogen atoms, therefore they are polar protic solvents. Hexane does not have any such hydrogen atoms, therefore it is non-polar. DMSO has sulfoxide as the functional group which is polar aprotic in nature, therefore it is not a polar protic solvent.
