D) None of the above

$\textbf{Hydrogen}$ is the name given to the bond between water molecules.

Answer 2

Answer:

The bond formed between water molecules is hydrogen bond.

Therefore, the option (C) is correct.

Explanation:

Hydrogen bond is a type of bond which is formed between hydrogen and a highly electronegative atom. These bonds are less stronger in the comparison of ionic bond or covalent bonds. But hydrogen bonds are stronger than Vander Waals force of attraction.

• Hydrogen bonds are divided into two categories: Intramolecular hydrogen bond and intermolecular hydrogen bond. When the hydrogen bond formed within the same molecule is known as intramolecular hydrogen bond. This type of hydrogen bonding is found in ethylene glycol.
• When the hydrogen bond is formed between two same or different molecule is known as intermolecular hydrogen bond. The hydrogen bonding present in water is intermolecular hydrogen bonding.
• In a water molecule, two hydrogen atoms linked to a highly electronegative oxygen atom. The bond pair electrons are more attracted by the oxygen atom in comparison of H-atom because of its high electronegativity.
• As result, the hydrogen atoms become positive and oxygen end of the molecule becomes negative. The attraction between negatively charged oxygen of another molecule and partially positively charged hydrogen of one water molecule leads to formation of hydrogen bonds.

• Maximum four hydrogen bonds can be formed by one water with other water molecules.

Therefore, the molecules of water  stick together in liquid water because of hydrogen bonds.
