Question

what are hydrogen bonds?
a strong bonds between the oxygen atom of one water molecule and a hydrogen atom of another.
b weak bonds between the hydrogen atoms of water molecules.
c weak bonds between the oxygen atom of one water molecule and a hydrogen atom of another.
d strong bonds between the hydrogen atoms of water molecules.

Explanation:

To determine the correct answer, we analyze the nature of hydrogen bonds:

• Hydrogen bonds are weak intermolecular forces, not strong covalent or ionic bonds, so options a and d (which mention "strong bonds") are incorrect.
• Hydrogen bonds form between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule, not between hydrogen atoms of water molecules (so option b is incorrect).
• Option c correctly describes hydrogen bonds as weak bonds between the oxygen atom of one water molecule and a hydrogen atom of another.

Answer:

c. Weak bonds between the oxygen atom of one water molecule and a hydrogen atom of another.
