Answer:
A water molecule can bond to up to four other water molecules by hydrogen bonds.
Explanation:
A water molecule has angular structure about the oxygen atom which has 2 lone pair of electrons in a water molecule. Due to the repulsion of lone pairs we get the angle between the H---O bond as 109.47°.
Each of the hydrogen atom of water attracts one water molecule and the partial negative on the oxygen atom attracts two more water molecules form the electron deficit side to form a pentamer of tetrahedral structure placing itself at the center of the geometry and the bonded molecules at the vertices.
A hydrogen bond is an intermolecular bond. A water molecule bonds up to 4 water molecules by the hydrogen bond.
Hydrogen bond:
- It is an intermolecular bond that is formed between molecules that have a high difference in electronegativity.
- A water molecule has two hydrogens. These hydrogens, bond with the oxygen of another water molecule.
- The oxygen can bond the 2 hydrogens.
Therefore, a water molecule bonds up to 4 water molecules by the hydrogen bond.
