Chemical bond
CHEMICAL BOND · IMAT Doutor1 / 1
Water boils at 100 degrees Celsius while hydrogen sulfide, a heavier molecule, boils at about minus 60. The best explanation is that:
A
Water molecules are held by covalent bonds to each other, which must be broken for the liquid to boil
B
Water has a higher molar mass, so more energy is needed to move its molecules apart into the gas phase
C
Water molecules are ionic, so they attract each other much more strongly than those of hydrogen sulfide
D
Hydrogen sulfide is a solid at room temperature, so its boiling point cannot be compared with that of water
E
Water molecules are held together by hydrogen bonds, which sulfur is not electronegative enough to form
