Question

1) I need to know why water has a higher boiling point than expected because

A. there is so much water vapor in the atmosphere.

B. water molecules are not very massive.

C. hydrogen and oxygen form single covalent bonds.

D. of the strong attractions between polar water molecules



2) Because water molecules are polar and carbon dioxide molecules are nonpolar,

A. water has a lower boiling point than carbon dioxide does.

B. attractions between water molecules are weaker than attractions between carbon dioxide molecules.

C. carbon dioxide cannot exist as a solid.

D. water has a higher boiling point than carbon dioxide does

Answer 1

In my opinion, the correct answer for the first question is option D. Water has a higher boiling point than expected because of the strong attractions between polar water molecules which is the hydrogen bonding. For question number two, the correct answer is option D. Water has a higher boiling point than carbon dioxide does.
