Aromatic
Definition:
Aromatic compounds are organic compounds that exhibit a cyclic structure with alternating single and double bonds. These compounds are characterized by their distinct and often pleasant smells.
Characteristics:
- Ring structure: Aromatic compounds contain one or more benzene rings in their molecular structure.
- Conjugated Ï€ bonds: The alternating single and double bonds in the ring create a system of conjugated Ï€ bonds, which contribute to the compound’s stability and unique properties.
- Distinct odor: Aromatic compounds are often associated with strong and recognizable smells. Many natural and synthetic fragrances are derived from aromatic compounds.
- Chemical stability: Due to the resonance stabilization provided by the delocalized π system, aromatic compounds are relatively inert and less reactive compared to non-aromatic compounds.
- Electron delocalization: The delocalized π electrons in aromatic compounds are spread across the entire ring system, creating a stable electron cloud.
Examples:
Some common examples of aromatic compounds include:
- Benzene
- Toluene
- Aniline
- Naphthalene
- Phenol
