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

a. water forms weak hydrogen bonds.
b. water forms strong hydrogen bonds.
c. water has weak cohesive forces.
d. water has strong adhesive forces.

B

Water forms strong hydrogen bonds.

B. Water forms strong hydrogen bonds.

Explanation:

The forces between the molecules of similar substances are called as cohesive forces and the forces between the molecules of different  substances are called as adhesive forces.

Boiling point is the temperature at which vapor pressure of the liquid becomes equal to atmospheric pressure.

Boiling point depends on the strength of inter molecular forces. The molecules of water are bonded through strong hydrogen bonds between electropositive hydrogen and electronegative oxygen and thus have strong cohesive forces.

In order to make the vapor pressure equal to atmospheric pressure, the liquid needs to be heated more and thus has higher boiling point.
