Which statement explains why hydrogen bonds are able to form between water molecules?
Water molecules are polar.
Water molecule atoms have weak atomic bonds..
Water molecules show adhesion.
Water molecules are large.

Respuesta :

Answer:

Water molecules are polar.

Explanation:

Hydrogen Bonds  - Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond.

This bond is very weak. Hydrogen bonds are formed easily when two water molecules come close together, but are easily broken when the water molecules move apart again. They are only a small fraction of the strength of a covalent bond, but, there are a lot of them

The fact that water molecules are POLAR makes it possible for hydrogen bonds to form between them.

HOW IS WATER POLAR?

  • Water is a chemical compound made up of two hydrogen atoms and one oxygen atom i.e. H2O. The hydrogen atoms are electropositive while the oxygen atom is electronegative.

  • The electronegativity of the oxygen atom allows the positive hydrogen ions to be attracted towards it. This makes water molecules polar.

  • Hydrogen bonds form when hydrogen ions (H+) are attracted to an electronegative ion like 02-, S2- etc. Hence, in the interaction of water molecules, the hydrogen ion of one water molecule gets attracted to the oxygen ion of another water molecule, hence, forming HYDROGEN BOND.

In a nutshell, hydrogen bonding is possible in water due to its polariry.
