Question

Molecules of water are held together by hydrogen bonds. This mutual intermolecular attractive force is called _______.

• A. adhesive force
• B. cohesive force
• C. capillarity
• D. imbibition

Answer 1

The correct option is B cohesive force

The intermolecular attractive forces between molecules of the same type, water molecules in this context, which hold them together is called cohesion. Adhesion is the attractive forces between different types of molecules, that is water and the capillary walls.
Capillarity is the tendency of a liquid in a capillary tube or absorbent material to rise or fall as a result of surface tension. The capillarity of water is due to its cohesive and adhesive forces.
