Question

what gives water most of its unique properties? a the polarity between the oxygen and hydrogens b the oxygen in its molecular structure c hydrogen bonding between water molecules d its high boiling point

Explanation:

To determine what gives water most of its unique properties, we analyze each option:

• Option a: The polarity within the water molecule (between O and H) is a factor, but the intermolecular forces (hydrogen bonding) from this polarity are more responsible for unique properties like high specific heat, cohesion, etc.
• Option b: Oxygen in the molecular structure is part of water's formula, but many molecules with oxygen don't have water's unique properties, so this is not the main reason.
• Option c: Hydrogen bonding between water molecules (resulting from the polar O - H bonds) is the key. It causes properties like high boiling point, high surface tension, cohesion, adhesion, and the ability to dissolve many substances.
• Option d: A high boiling point is a property of water, not the cause of its unique properties. The hydrogen bonding causes the high boiling point.

So the correct answer is the one related to hydrogen bonding between water molecules.

Answer:

c. hydrogen bonding between water molecules
