The addition of HCl in the presence of peroxide does not follow anti-Markovnikov rule because

Correct answer: A. HCl bond is too strong to be broken homolytically

  • A. HCl bond is too strong to be broken homolytically
  • B. Cl atom is not reactive enough to add on to a double bond.
  • C. Cl combines with H to give back HCl
  • D. HCl is a reducing agent

Explanation

Peroxides can act as radical initiators and generate highly reactive chlorine radicals (Cl•) from HCl. These radicals can add to the alkene, leading to the formation of a radical intermediate. This radical pathway results in the addition of the chlorine atom to the less substituted carbon of the double bond, contrary to the Markovnikov rule.

About Chemistry of Hydrocarbons

Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
