Which of the following is most reactive to give electrophilic addition reactions ?
Correct answer: B. Alkene
- A. Alkane
- B. Alkene
- C. Benzene
- D. Alkyne
Explanation
Electrophilic addition occurs at π-bonds, which are electron-rich and easily attacked by electrophiles. Alkenes have a double bond, making them more reactive than alkanes, alkynes (less reactive in some conditions), or benzene (stabilized by resonance). Hence, alkenes are the most reactive in electrophilic addition reactions.

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.
