Trichlorobenzene Isomers

Compounds with the chemical formula C6H3Cl3, consisting of a benzene ring substituted with three chlorine atoms, existing in different structural configurations.

Aromatic

Refers to organic compounds that contain one or more benzene rings in their structure, characterized by their stability and aromaticity.

Antiaromatic

Nonaromatic

Refers to organic compounds that do not possess the delocalized pi-electron system characteristic of aromatic compounds, often resulting in different chemical properties.
