Some examples of organic compounds that contain the benzene ring are benzene itself, toluene, phenol, aniline, and styrene. These compounds are aromatic hydrocarbons that share the characteristic hexagonal structure of the benzene ring.
Benzopyran is a heterocyclic compound that consists of a benzene ring fused to a pyran ring. It is found in various natural products and pharmaceutical compounds, exhibiting diverse biological activities. Benzopyrans are known for their antioxidant, anti-inflammatory, and anticancer properties.
Alicyclic compounds are organic compounds that contain rings, but do not have the properties of aromatic compounds. These compounds can be saturated or unsaturated and may contain heteroatoms like oxygen or nitrogen in the ring. Examples include cyclohexane and cyclopentane.
Antiaromatic compounds have a fully conjugated ring system with 4n electrons, making them highly unstable and reactive. Nonaromatic compounds do not have a fully conjugated ring system or have an odd number of electrons, making them more stable. Aromatic compounds have a fully conjugated ring system with 4n2 electrons, making them stable and less reactive than antiaromatic compounds.
Carbazole is an aromatic heterocyclic organic compound. It has a tricyclic structure, consisting of two six-membered benzene ring fused on either side of a five-membered nitrogen-containing ring.
Aromatic compounds contain a benzene ring or any other planar ring system with delocalized pi electrons that follows Hückel's rule.
A benzazepine is any of the class of heterocyclic compounds consisting of a benzene ring fused to an azepine ring.
Fused heterocylic compounds is a heterocylic compound (eg. Furan) fused with another ring which can be either a carbon ring (benzene) or can be fused with another heterocylic ring(Pyridine,Pyrrole,...etc). Fused heterocyclics can be either 2 fused rings,3 rings or more. From the famous examples on fused heterocylic compounds: -Heroin -Indole -Morphine -Carbazole

aromatic compound
Psilocybin mushrooms contain the functional group known as a tryptamine, which consists of an indole ring fused to an ethylamine chain. The psychoactive compounds in these mushrooms, such as psilocybin and psilocin, are derived from tryptamine.

Steroid refers to the group name for lipids that contain a hydrogenated cyclopentanoperhydrophenanthrene ring system.
A gibbane ring is a type of plant growth hormone or compounds containing a gibbane ring system, e. g. gibberellin.
