State and explain Markonikoff's rule with suitable example . |
Answer» Solution :Markownikoff's rule : " When an unsymmetrical alkene is treated with an unsymmetrical REAGENT (HX), then the negative PART of the reagent (-X) gets added to that unsaturated carbon of the double bond, which contains lesser no. of hydrogen atoms . " <BR> Eg ., here , an unsymmetriacal reagent HBr is added to an unsymmetrical alkene like 2 - METHYL -2 - butene , the negative part `(Br^(-))` is attached to that carbon atom which have lesser no. of hydrogen atom and forms a ocompund 2 - bromo - 2 - methylbutane. Here, Br add to `C_(2)` of 2 - methyl - 2 - butene which has lesser no. of hydrogen atoms . |
