Aromatic hydrocarbon

Aromatic hydrocarbon refers to a class of carbon-hydrogen compounds with cyclic molecular structures, typical representatives including benzene and toluene. These compounds are commonly found in substances such as gasoline, and they produce noticeable black smoke when burned. Compared to aliphatic compounds, aromatic hydrocarbons have significantly higher carbon content. Their molecular structure exhibits a unique arrangement of alternating single and double bonds in a ring, which makes them difficult to react with ordinary oxidizing or reducing agents.

Under standard conditions, aromatic compounds are reluctant to undergo addition reactions but readily undergo substitution reactions. Their characteristics also manifest as excellent thermal stability and specific chemical behavior: thermal stability endows aromatic hydrocarbons with greater heat absorption capacity, which contrasts sharply with other compounds that release high heat upon combustion; while chemical behavior is reflected in the reactions they undergo with specific reagents.
