Witrynabenzene ring: [noun] a structural arrangement of atoms in benzene and other aromatic compounds that consists of a planar symmetrical hexagon of six carbon atoms which derives added stability from the delocalization of certain bonding electrons over the entire ring — compare meta- 4a, orth- 4b, para- 2b.
Benzene ring Britannica
WitrynaThe carbon "ring" is what makes benzene "aromatic". Aromatic compounds, also known as "mono- and polycyclic aromatic hydrocarbons ", [1] are organic compounds containing one or more aromatic rings. The word "aromatic" originates from the past grouping of molecules based on smell, before their general chemical properties are understood. WitrynaA benzene ring is highly stable because of the aromaticity that hardly allows it to undergo the ring-opening reaction. In contrast, heterocyclic compounds are not as … port of israel
