How many π electrons are there in benzene to form delocalized electronic cloud?
Correct answer: D. 6
- A. 3
- B. 4
- C. 8
- D. 6
Explanation
Each of the six sp²-hybridized carbon atoms in the benzene ring contributes one electron from its unhybridized p-orbital to the pi system. This results in a total of 6 t electrons that are delocalized in a continuous cloud above and below the plane of the ring.

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.
