Electronegativity is a measure of an atom`s ability to attract shared electrons to its side. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

Oxygen is more electro negative then Hydrogen it pulls the shared electron to its side.
