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.
