The distinguishing feature of aromatic hydrocarbons is their unique structure, characterized by the presence of one or more benzene rings, which consist of six carbon atoms arranged in a planar hexagonal ring with alternating single and double bonds. This arrangement leads to resonance stabilization, allowing for delocalized π electrons across the ring, which contributes to their chemical stability and distinct reactivity. Aromatic compounds typically exhibit characteristic odors and are often found in natural substances as well as in various industrial applications.

Alternating single and double bonds
Hydrocarbons with a circular structure are known as cyclic hydrocarbons. Examples include cycloalkanes, such as cyclopropane, cyclobutane, cyclopentane, and cyclohexane. These compounds contain carbon atoms arranged in a ring, with single or double bonds between them. Aromatic hydrocarbons, like benzene, also have a cyclic structure and feature alternating double bonds within their rings.
Aromatic hydrocarbons, specifically benzene and its derivatives, belong to the class of unsaturated hydrocarbons with a ring structure. These compounds exhibit special stability due to the delocalization of pi electrons within the ring, making them distinct from aliphatic hydrocarbons.
Principal characteristics of aromatic hydrocarbons are:- the contain benzenic rings- frequently they have an agreeable odor- they burn with soot; this is a disadvantage- the ratio carbon/hydrogen is great
Aliphatic hydrocarbons have straight or branched carbon chains, while aromatic hydrocarbons contain a benzene ring or other aromatic rings in their structure. Aliphatic hydrocarbons are typically less stable and more reactive than aromatic hydrocarbons due to differences in bond types and energy. Aromatic hydrocarbons exhibit unique properties such as resonance stabilization and are often used as precursors for various organic compounds.
Gasoline is a mixture of both aromatic and aliphatic hydrocarbons. Aromatic hydrocarbons such as benzene, toluene, and xylene are present in small amounts, while the majority of components are aliphatic hydrocarbons like octane, heptane, and pentane.
