Which of the following is a property of liquid water?
A
Inability to form hydrogen bonds
B
Repulsion between water molecules
C
Cohesion between water molecules due to hydrogen bonding
D
Lack of surface tension
Verified step by step guidance
1
Understand the concept of hydrogen bonding: Hydrogen bonds are weak interactions that occur between a hydrogen atom covalently bonded to an electronegative atom (like oxygen) and another electronegative atom. In water, these bonds form between the hydrogen of one water molecule and the oxygen of another.
Recognize the property of cohesion: Cohesion refers to the attraction between molecules of the same substance. In water, this is due to hydrogen bonding, which allows water molecules to stick together.
Analyze the options: Eliminate incorrect choices. For example, 'Inability to form hydrogen bonds' is incorrect because water molecules readily form hydrogen bonds. Similarly, 'Repulsion between water molecules' is incorrect because water molecules attract each other due to hydrogen bonding. 'Lack of surface tension' is also incorrect because water has high surface tension due to cohesive forces.
Identify the correct property: The correct property is 'Cohesion between water molecules due to hydrogen bonding,' as this explains the strong intermolecular forces that give water its unique properties.
Conclude: The property of cohesion in water is a result of hydrogen bonding, which is responsible for phenomena like surface tension and the ability of water to form droplets.
