Acenaphthenes - Tricyclic ethylene-bridged naphthalene derivatives. They are found in petroleum residues and coal tar and used as dye intermediates, in the manufacture of plastics, and in insecticides and fungicides. |
|
Anthracenes - A group of compounds with three aromatic rings joined in linear arrangement. |
|
Benzocycloheptenes |
|
Fluorenes - A family of diphenylenemethane derivatives. |
|
Indenes - A family of fused-ring hydrocarbons isolated from coal tar that act as intermediates in various chemical reactions and are used in the production of coumarone-indene resins. |
|
Naphthacenes - Polyacenes with four ortho-fused benzene rings in a straight linear arrangement. This group is best known for the subclass called TETRACYCLINES. |
|
Naphthalenes - Two-ring crystalline hydrocarbons isolated from coal tar. They are used as intermediates in chemical synthesis, as insect repellents, fungicides, lubricants, preservatives, and, formerly, as topical antiseptics. |
|
Phenalenes - A group of AROMATIC HYDROCARBONS that have three rings joined as a triad around a single carbon atom so all three are conjoined, in contrast to a linear arrangement (ANTHRACENES) or angular arrangement (PHENANTHRENES). |
|
Phenanthrenes |
|
Pyrenes - A group of condensed ring hydrocarbons. |
|
Spiro Compounds - A group of compounds consisting in part of two rings sharing one carbon atom in common. |
