* Oxygen is more electronegative than hydrogen: This means oxygen has a stronger pull on the shared electrons in the O-H bonds.
* Bent molecular geometry: The two hydrogen atoms are not positioned directly opposite each other. This creates a bent shape, with the oxygen atom at the "peak" of the bend.
* Uneven charge distribution: Because oxygen is more electronegative, it pulls the shared electrons closer to itself, creating a partial negative charge (δ-) on the oxygen atom. This leaves the hydrogen atoms with a partial positive charge (δ+).
* Dipole moment: This separation of charge creates a dipole moment, where one end of the molecule is slightly negative and the other end is slightly positive.
In summary: The combination of oxygen's higher electronegativity and the bent shape of the water molecule results in an uneven distribution of charge, making water a polar molecule.
