What are the key differences between a benzene ring and an aromatic ring?

A benzene ring is a specific type of aromatic ring. The key difference is that a benzene ring consists of six carbon atoms connected in a hexagonal shape with alternating single and double bonds, while an aromatic ring can have different numbers of carbon atoms and may not necessarily have the same alternating bond pattern as benzene. Benzene is a type of aromatic compound, but not all aromatic compounds have a benzene ring structure.
