Polar vs. Non polar Covalent Bonds PolarCovalent bonds- H — F electrons are shared unequally Non polar covalent bonds- H — H electrons shared equally Which bonds are polar F O N Cl bonded to another type of atom any other type of bond is non polar POLAR COVALENT BONDS (between F.O.N.Cl. and non F.O.N.Cl.) + H — F — F.O.N.Cl. end of the bond is negative (-) Non F.O.N.Cl. end of the bond is positive (+)
