Which of the following is responsible for the cohesion of water molecules?

Question

Quizplus · Accepted Answer

Hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule are responsible for the cohesion of water molecules. This cohesion creates surface tension, allowing water to form droplets and move upward through the xylem in plants. Option A is incorrect because cellulose does not form hydrogen bonds with water molecules to create cohesion. Option B and D are incorrect because covalent bonds do not form between water molecules, only polar covalent bonds within individual water molecules. Option E is incorrect because while tight packing does contribute to cohesion in a sense, it is the hydrogen bonds between water molecules that actually hold them together.
