Hydrogen bonding in water accounts for
A)water's higher than expected boiling temperature.
B)the fact that ice floats in liquid water.
C)the fact that snowflakes are 6-sided.
D)All of the above.

Question

Quizplus · Accepted Answer

Hydrogen bonding is responsible for all three of the given features of water: 
- water's higher than expected boiling temperature is due to the strong hydrogen bonding between water molecules, which requires more energy to break apart and boil the water. 
- the fact that ice floats in liquid water is due to the unique structure of the hydrogen bonds, which causes the water molecules to form a lattice that is less dense than liquid water. 
- the 6-sided shape of snowflakes is also due to the hydrogen bonding between water molecules, which causes them to form a repeating, symmetrical pattern as they freeze and crystallize.
