Question

8)What is Huckel rule? Explain it in benzene​

Answer 1

Answer:

Illustrated Glossary of Organic Chemistry - Term. Huckel's Rule (4n+2 rule): In order to be aromatic, a molecule must have a certain number of pi electrons (electrons with pi bonds, or lone pairs within p orbitals) within a closed loop of parallel, adjacent p orbitals.

Huckel's Rule. Simply put, Huckel's rule for aromaticity states that a monocyclic system will be aromatic if there are 4n + 2 delocalised electrons, (n an integer) contained within it. ... Benzene, on the other hand, has all 6 pi electrons in bonding orbitals, and through this achieves extra stability
