The synthesis of olefin and the application of oxidation of C=C

The property of olefin with more alkyl on both sides of C=C is more stable and The heat of hydrogenation of it is lower.As a result,halogenated hydrocarbon commonly loses hydrogen from the carbon with lesser hydrogen atoms.The oxidation of olefin by kalii permanganate is very important.A simple memory method makes students understand and command the synthesis of olefin and oxidation of C=C.
