Double Bond

                        A covalent bond formed between two atoms by the mutual sharing of two electron pairs is called double bond.Double bonds are drawn as two parallel lines in chemical structure diagrams. Double bonds are shorter than single bond.The bond order is two.Double bonds are also electron rich , which makes them reactive.

           Ethylene (C2H4) is a hydrocarbon with a double bond between the two carbon atoms.
