The Importance of Water

Question 9 • AZ-Physical Science A-CR

Which statement explains why hydrogen bonds are able to form between water molecules?

Answer
A
Water molecules are polar.
B
Water molecule atoms have weak atomic bonds..
C
Water molecules show adhesion.
D
Water molecules are large.

Explanation

Water molecules are polar: oxygen has a partial negative charge, while the hydrogen atoms have partial positive charges. The attraction between a partially positive hydrogen on one water molecule and a partially negative oxygen on another forms a hydrogen bond. Adhesion describes water sticking to other materials, and molecule size does not explain hydrogen bonding.
