The unhybridized p orbitals of benzene are present _.
Correct answer: C. In the form of a cloud above and below the benzene ring
- A. Between the C-C bonds of benzene
- B. Above and below the carbon bonds
- C. In the form of a cloud above and below the benzene ring
- D. None of these options is correct
Explanation
All of the carbon atoms in the benzene rings are sp2-hybridized: the overlap of the sp2 orbitals around the ring produces a framework of six sigma bonds, while the unhybridized p-orbitals are perpendicular to this plane overlapping in a side-to-side fashion to form three pi-bonds.

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.
