Question

the polarity of water molecules
a water molecule, as shown here, is polar because
multiple choice
of its ability to form hydrogen bonds.
of the transfer of electrons.
of its ability to freeze.
electrons spend more time near the hydrogen nuclei than near the oxygen nuclei.
oxygen has a stronger electronegativity than hydrogen.

Explanation:

1. Analyze the first option: The ability to form hydrogen bonds is a result of water's polarity, not the cause of it. So this option is incorrect.
2. Analyze the second option: In a water molecule, electrons are shared (covalent bond), not transferred (which is for ionic bonds). So this option is incorrect.
3. Analyze the third option: The ability to freeze is a physical property related to phase change, not related to the polarity of the water molecule. So this option is incorrect.
4. Analyze the fourth option: Oxygen is more electronegative than hydrogen, so electrons in the O - H bonds spend more time near the oxygen nucleus, not the hydrogen nuclei. So this option is incorrect.
5. Analyze the fifth option: Electronegativity is the ability of an atom to attract electrons. Oxygen has a stronger electronegativity than hydrogen. In the water molecule (\(H_2O\)), the shared electrons in the covalent bonds between oxygen and hydrogen are pulled more towards the oxygen atom. This creates a partial negative charge on the oxygen and partial positive charges on the hydrogens, resulting in a polar molecule. So this option correctly explains the polarity of the water molecule.

Answer:

The correct option is: oxygen has a stronger electronegativity than hydrogen.
