Question

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

Hydrogen bonds are weak intermolecular forces. In water (\(H_2O\)), the oxygen atom (which is electronegative) of one water molecule is attracted to the hydrogen atom of another water molecule. These are not covalent (strong) bonds within a single water molecule (like \(O - H\) bonds in \(H_2O\)), but rather weak interactions between different water molecules.

Answer:

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