oxygen! it pulls the hydrogen atoms toward it. therefore a water molecule is polar.

In a water molecule i.e H2O , O - Oxygen is the main electronegative. consequence : Formation of hydrogen bond. This makes the electronegative O to form a partial bond ( hydrogen bond ) with H atom .

oxygen has an electronegativity of 3.5 and hydrogen has 2.1. A good way to remember this is to remember that

oxygen=3.5 on the Pauling scale. Hydrogen = 2.4
