Resembling or containing benzene rings; describing aromatic compounds with the stable ring structure characteristic of benzene.
From 'benzene' + '-oid' (Greek suffix meaning 'resembling' or 'like'). This term developed in organic chemistry to classify compounds based on their structural similarity to benzene.
Benzenoid molecules are remarkably stable because of something called aromaticity—the electrons in the ring are unusually secure, which is why benzene-based compounds show up everywhere from dyes to pharmaceuticals to materials.
