According to atomic orbital treatment of benzene, all of the following statements are correct about benzene EXCEPT:
Correct answer: D. It has 6 sigma bonds and 6 pi electrons
- A. In it each carbon atom has sp2-orbital hybridization
- B. It is cyclic hexagonal planar structure
- C. It has diffused or decolonized electron cloud
- D. It has 6 sigma bonds and 6 pi electrons
Explanation
The correct answer is Option D. While the statement in Option D correctly mentions the 6 pi electrons in benzene, it incorrectly states that benzene has 6 sigma bonds. In reality, benzene has 6 sigma bonds within the ring and 3 pi bonds, totaling 6 pi electrons. This makes Option D the correct answer choice. The other options correctly describe various aspects of benzene's structure and bonding characteristics.
