What is Polar Covalent Bond?
A polar covalent bond is a covalent bond between two atoms of different electronegativities, resulting in unequal sharing of the bonding electrons. The more electronegative atom attracts the electrons more strongly, acquiring a partial negative charge (δ−), while the less electronegative atom acquires a partial positive charge (δ+). The degree of polarity is measured by the bond dipole moment.
