Addition of unsymmetrical reagent to an unsymmetrical alkene is governed by:
Correct answer: D. Markownikov's Rule
- A. Cannizzaro's Reaction
- B. Kirchhoff Rule
- C. Aldol Condensation
- D. Markownikov's Rule
Explanation
The addition of unsymmetrical reagents to unsymmetrical alkenes follows Markovnikov's rule. This rule dictates that the negative part of the reagent will attach to the unsaturated carbon atom with fewer hydrogen atoms. For example, the addition of hydrogen bromide to propene results in isopropyl bromide as the major product due to Markovnikov's rule.The other options are incorrect as they describe different reactions or rules that are not relevant to the addition of unsymmetrical reagents to unsymmetrical alkenes.

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.
