Answer to Question #118450 in Chemistry for Angelina

Question

Which of the following is not true?

Hydrogen bonding helps explain why solid water floats on liquid water.
Hydrogen bonding is responsible for the relatively low boiling point of water.
Water molecules are farther apart in solid water than they are in liquid water.
Hydrogen bonding is responsible for the relatively high boiling point of water.

Answer 1

Hydrogen bonding is responsible for the relatively low boiling point of water.

This statement is not true. Although hydrogen bonds are weak, the high number of these interactions significantly increase the boiling point of water as more energy is required to transform liquid water to water vapour. As a result, hydrogen bonding is responsible for the relatively high boiling point.
