Study Notes
Aromatic Compounds
- The defining characteristic of aromatic compounds is the presence of a planar, ring-shaped structure with delocalized electrons.
- The term 'Aromatic' was proposed by August Wilhelm von Hofmann in 1855.
Representation of Benzene
- Benzene is commonly represented by a hexagonal ring structure with a circle in the center, indicating the delocalized electrons.
Classification of Aromatic Compounds
- Aromatic compounds are a type of hydrocarbons.
Functional Groups in Aromatic Compounds
- The defining feature of the functional groups in aromatic compounds is the presence of delocalized electrons, which leads to increased stability and unique properties.
Origin of the Term 'Aromatic'
- Aromatic compounds were originally named 'aromatic' due to their pleasant, sweet odors.
