Water is a Polar Molecule Because

Question

Water is a polar molecule because:
A) oxygen is more electronegative than hydrogen.
B) hydrogen has more neutrons than oxygen.
C) oxygen has more electrons than hydrogen.
D) oxygen has more neutrons than hydrogen.
E) hydrogen is more electronegative than oxygen.

Accepted Answer

Water is a polar molecule because oxygen is more electronegative than hydrogen. This means that oxygen has a stronger pull on the shared electrons in the covalent bond between hydrogen and oxygen, creating a partial negative charge around the oxygen atom and a partial positive charge around the hydrogen atoms. This unequal sharing of electrons creates a polar molecule.
