✦ Synopsis
The oxidation reaction between 8-hydroxyquinoline and hydrochloric acid yields 6,6,7,7-tetrachloro-5,6,7,8-tetrahydroquinoline-5,8-dione, C~9~H~3~Cl~4~NO. The non-aromatic part of the fused ring is non-planar; one of the chlorine-substituted C atoms lies above the mean plane of the fused ring, whereas the other lies below it.
