What is polar covalend?

Answer 1

Polar covalent bonds occur when two atoms with differing electronegativities share electrons unequally, resulting in a molecule with a slight electrical dipole moment. In these bonds, the atom with higher electronegativity attracts the shared electrons more strongly, leading to a partial negative charge (δ-) on that atom and a partial positive charge (δ+) on the other. Water (H₂O) is a classic example, where the oxygen atom is more electronegative than hydrogen, creating a polar molecule. This polarity influences many of the molecule's properties, including its solvent capabilities and boiling point.
