Addition reactions

Addition reactions are those reactions in which one reactant molecule adds on to multiple bond of another moleculeIt is characteristic of unsaturated compounds eg:- addition of hydrogen to etheneThe characteristic reaction of alkene is electrophilic substitution reactions Addition of HydrogenAlkenes add hydrogen in presence of Ni, Pt or Pd as catalyst. This process is hydrogenation Addition of halogensAlkene react with halogens to form di halogen derivatives Addition of nitrosyl chloride Alkene add nitrosyl chloride at the double bond to form alkyl nitroso chloride

Addition of waterWater adds to alkene in presence of mineral acids to form alcohols Addition of hydrogen halideAlkene react with hydrogen halides to form haloalkenes HydroborationAdditin of diborane to alkene give trialkyl borane

Addition of sulfuric acidCold concentrated sulfuric acid reacts with alkene to form alkyl hydrogen sulfate AlkylationAlkene add alkane in presence of acid catalyst like sulfuric acidThank you
