Addition reaction of hydrogen Bromide to the unsymmetrical alkene follows _
Correct answer: B. Markovnikov's rule
- A. Anti-Markovnikov's rule
- B. Markovnikov's rule
- C. Kharish effect
- D. Peroxide effect
Explanation
According to Markovnikov's rule, during the addition of hydrogen bromide (HBr) to an unsymmetrical alkene, the hydrogen atom will attach to the carbon with more hydrogen atoms, and the bromine will attach to the carbon with fewer hydrogen atoms. This results in a more stable carbocation intermediate which is crucial for the reaction to proceed. The other options describe conditions or effects that are either incorrect without specific conditions (Anti-Markovnikov's rule with peroxides) or unrelated (Kharish effect).

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.
