Question 16 • Chemistry

Which best explains why water has a much higher boiling point than would otherwise be predicted?

Answer
A
Water forms weak hydrogen bonds.
B
Water has strong adhesive forces.
C
Water forms strong hydrogen bonds.
D
Water has weak cohesive forces.

Explanation

Water molecules attract one another through strong hydrogen bonds. Extra energy is needed to overcome these attractions and separate the molecules into a gas, which raises water’s boiling point. Therefore, the best answer is that water forms strong hydrogen bonds.
