Water exhibits a unique property of surface tension. What happens among 1P

the water molecules to cause this property to occur? *

O

The water molecules begin to spread out rapidly near the surface of the water.

O

The water molecules are nonpolar and repel each other near the surface of the water.

O

The water molecules are strongly attracted to each other through hydrogen bonding.

O

The water molecules do not move very quickly near the surface of the water.

C. The water molecules are strongly attracted to each other through hydrogen bonding.

Explanation:

Water molecules have strong intermolecular force of attraction due to the presence of hydrogen bond between oxygen and hydrogen atoms. This hydrogen bond is present between hydrogen of one water molecule to the oxygen of another water molecule. This hydrogen bond is weaker than covalent bond so that's why it can be broken down and water is converted into vapours form by heating. Both oxygen and hydrogen have different electronegativity values so partial positive charge occurs on oxygen while partial negative charge occurs on hydrogen atom.
