B) Water forms dispersion forces, and methane forms hydrogen bonds. C) Water has a higher molecular weight than methane. D) Methane has a higher molecular weight than water. E) Methane has more atoms than water.

Question

Quizplus · Accepted Answer

Water forms hydrogen bonds due to the presence of hydrogen atoms bonded to a highly electronegative oxygen atom, which gives it a higher boiling point and makes it a liquid at room temperature. Methane, on the other hand, can only form weaker dispersion forces, which is why it is a gas at room temperature.
