Why is a water.molecule.polar?

A water molecule is polar due to its bent shape and the difference in electronegativity between the oxygen and hydrogen atoms. Oxygen is more electronegative, causing it to attract shared electrons more strongly, which creates a partial negative charge near the oxygen and a partial positive charge near the hydrogen atoms. This uneven distribution of charge results in a dipole moment, making water a polar molecule. Additionally, the polarity of water contributes to its unique properties, such as high surface tension and solvent capabilities.
