Hydrogen bonding causes cohesion and thermal properties in water

Steps:

• Recall hydrogen bonding forms between water's partial charges, creating strong intermolecular attractions.
• Property 1 likely involves polarity or dipole moment alone, not requiring H-bonds between molecules.
• Property 2 involves cohesion from H-bonds, like surface tension enabling capillary action.
• Property 3 involves H-bonds stabilizing structure, like ice's lower density than liquid water.

Why C is correct:

• Hydrogen bonding directly causes properties 2 (cohesive forces) and 3 (anomalous expansion on freezing), per intermolecular force definitions.

Why the others are wrong:

• A includes 1, which stems from water's polarity, not H-bonding networks.
• B selects only 2, omitting 3's H-bond-driven lattice in ice.
• D selects only 3, omitting 2's H-bond cohesion.

Final answer: C
