|
Many of the unique properties of water can be attributed to the hydrogen bonding that occurs BETWEEN individual water molecules. A hydrogen bond is formed between two water molecules when:
|
|
The negative oxygen end of one water molecule is attracted to the positive hydrogen end of another water molecule.
|
|
|
The negative hydrogen end of one water molecular is attracted to the positive oxygen end of another water molecule.
|
|
|
A covalent bond is formed between the negative and positive poles of the water molecule.
|
|
|
An ionic bond is formed between the negative and positive poles of the water molecule.

Explanation:
Detailed explanation-1: -Due to the extensive hydrogen bonding, water has some emergent properties that impact life on Earth in many ways. These include: Cohesion, Adhesion, High surface tension, High specific heat, High Heat of vaporization, and the fact that ice floats (Ice is less dense as a solid than liquid water).
Detailed explanation-2: -Summary. Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
