Aromatic compound
Aromatic Compound
An Aromatic Compound or Aromatics (pronunciation: /əˌrɒməˈtɪk kɒmpaʊnd/) is a type of organic compound that contains a planar unsaturated ring of atoms that are connected by pi bonds. This term is often used to refer to compounds that have one or more aromatic rings.
Etymology
The term "aromatic" was assigned before the physical concept of aromaticity was fully understood. It was originally used to describe compounds that have a strong or pleasant smell. The term is derived from the Greek word 'aroma', which means 'spice'.
