Aromatic compounds are a class of organic compounds that contain a particular stable ring structure known as an aromatic ring. This ring consists of alternating double and single bonds, which create a resonance structure that results in unique stability and reactivity properties. Aromatic compounds are known for their distinctive smells and can be found in a variety of natural sources such as plants, flowers, and fruits. They are widely used in the pharmaceutical, chemical, and food industries for their diverse applications and properties. Aromatic compounds are a key area of study in organic chemistry due to their importance in a wide range of fields.
