Ice floats because of the electronegativity of oxygen that withdraws electron density from the covalently bonded hydrogens. This results in a permanent dipole, leaving a partial positive charge on the hydrogens. The extra electron density on the oxygen leaves a partial negative charge. Therefore, water is a polar molecule and has the ability to form hydrogen bonds. These properties explain many of water's characteristics, including why ice is less dense than liquid water.

Water has a higher boiling point than acetone does. Which of the following statements about water and acetone in the liquid state must be true? A B C The density of water is greater than that of acetone. The density of water is less than that of acetone. The attractions between particles in water are greater than those in acetone. D The attractions between particles in water are weaker than those in acetone.
Two liquids – one polar, one nonpolar – have the same molar mass. Which one has the higher boiling point? A. The polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions. B. They will have similar boiling points, since the dispersion forces depend upon molar mass. C. The nonpolar liquid will have the higher boiling point, since its molecules are more loosely held together. D. The nonpolar liquid will have the higher boiling point, since the polar molecules will repel each other and lower the boiling point. E. It is impossible to say without additional information.
