A. It has a lower boiling point than water, and is likely to have Which property explains the high surface tension of water?stronger electrostatic forces present between molecules than water.
B. It has a higher boiling point than water, and so it is like to be nonpolar covalent.
C. It has a higher boiling point than water, and is likely to have weaker electrostatic forces present between water molecules than water.
D. It has a higher boiling point than water, and is likely to have stronger electrostatic forces present between molecules than water.
