Which compound is the most reactive one:
Correct answer: B. Ethene
- A. Benzene
- B. Ethene
- C. Ethane
- D. Ethyne
Explanation
The π bond in ethene is weak compared to the sigma bond between the two carbons. This weakness makes the π bond and the overall molecule a site of comparatively high chemical reactivity to an array of different substances.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
