Identification of Aromatic Compounds

Aromatic compounds are a class of compounds characterized by their stability and unique bonding structure. One of the simplest and most well-known aromatic compounds is benzene, which has the molecular formula C₆H₆. Benzene includes a ring of carbon atoms with alternating single and double bonds, giving it potential resonance structures. This property makes it a significant topic in organic chemistry.
