Answer: When HBR is added to unsymmetrical alkenes in the presence of peroxide, 1-bromopropane is formed contrary to 2-bromopropane (according to Markovnikov’s rule). This reaction mechanism is known as Anti Markovnikov addition or Kharash effect.

WebJul 5, 2024 · This process was first explained by Morris Selig Karasch in his paper: 'The Addition of Hydrogen Bromide to Allyl Bromide' in 1933. 1 Examples of Anti-Markovnikov includes Hydroboration-Oxidation and Radical Addition of HBr. A free radical is any chemical substance with unpaired electron. WebApr 8, 2024 · Markovnikov rule states that when polar reagents undergo an additional reaction with unsymmetrical alkenes, the negative part of the addendum adds to the carbon atom having less number of hydrogen atoms. For example: R C H = C H 2 + H C l → R C H C l − C H 2 Here C l adds to the carbon having less number of hydrogen.
