Aromatic compounds contain a benzene ring from "summary" of NCERT Chemistry Class 11 - [CBSE Board] by Dr. S. C. Rastogi, ,Er. Meera Goyal
In organic chemistry, aromatic compounds are a special class of compounds that exhibit unique properties. These compounds are characterized by the presence of a benzene ring in their structure. The benzene ring consists of six carbon atoms arranged in a hexagonal ring with alternating single and double bonds. This delocalized electron cloud gives aromatic compounds their distinctive stability and reactivity. The concept of aromaticity is based on the Hückel rule, which states that a compound is aromatic if it has a planar, cyclic structure with 4n+2 π electrons, where n is a non-negative integer. This rule helps us determine whether a compound is aromatic, non-aromatic, or anti-aromatic based on the number of π electrons present in its structure. Aromatic compounds with 4n+2 π electrons are stable and exhibit unique properties such as resonance stabilization and enhanced reactivity. Aromatic compounds are known for ...
