Here's why:
* Covalent: The hydrogen and oxygen atoms share electrons to achieve a stable electron configuration.
* Polar: Oxygen is more electronegative than hydrogen, meaning it attracts the shared electrons more strongly. This creates a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms. This uneven distribution of charge makes the molecule polar.
