Polar covalent bond?? |
| Answer» Gud yogita<br>It is the bond formed b/w heteroatomic(different)molecules of diff electronegativity*. Charge shifts to more e-ve* element and +ve charge to less e-ve*Thus, positive and negative poles r produced and bond become completely polar bond.<br>Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.Example: Hydrogen chloride (HCl) molecule.The bonding of hydrogen and chlorine atoms leans more towards Cl atom because Cl is more electronegative in nature than the hydrogen. Thus the shared pair of electrons lies not exactly in between the bond but lean towards chlorine. Due to this Cl atom acquire a slight negative charge, and H atom acquire slight positive charge. | |
