What is a ring with a nitrogen called?
Nomenclature of Cyclic Ethers Ring compounds containing nitrogen, oxygen, sulfur, or other elements as ring atoms generally are known as heterocyclic compounds, and the ring atoms other than carbon are the hetero atoms.
What is a 5 membered ring with nitrogen?
Pyrrole, furan, and thiophene molecules each contain five-membered rings, composed of four atoms of carbon and one atom of nitrogen, oxygen, or sulfur, respectively. Pyridine and pyrrole are both nitrogen heterocycles—their molecules contain nitrogen atoms along with carbon atoms in the rings.
What is a 5 membered ring called?
The bicyclic compounds made of a pyrrole, furan, or thiophene ring fused to a benzene ring are called indole (or isoindole), benzofuran, and benzothiophene, respectively. …
What is a four membered ring called?
Azetidine, oxetane, and thietane—four-membered rings containing, respectively, one nitrogen, oxygen, or sulfur atom—are prepared by nucleophilic displacement reactions similar to those used to prepare the corresponding three-membered rings.
What is a carbon ring called?
Aromatic rings (also known as aromatic compounds or arenes) are hydrocarbons which contain benzene, or some other related ring structure. Benzene, C6H6, is often drawn as a ring of six carbon atoms, with alternating double bonds and single bonds: This simple picture has some complications, however.
What are 5 heterocyclic compounds?
The simplest of the five membered heterocyclic compounds are pyrrole, furan and thiophene, each of which contains single heteroatoms. The five membered ring contains more than one or two heteroatoms also such as azole, pyrrole, thiazole, thiadiazole, oxadiazole, triazene, etc.
Is a 6 membered heterocyclic compound?
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s)….Six-membered rings with two heteroatoms.
| Heteroatom | Saturated | Unsaturated |
|---|---|---|
| Nitrogen / nitrogen | Diazinane | Diazine |
| Oxygen / nitrogen | Morpholine | Oxazine |
What is a 3 carbon ring called?
For more complicated substituents, the benzene ring is named as a substituent, in which case it is called “phenyl.” For instance, an eight-carbon chain with a benzene ring on the third carbon is called “3-phenyloctane.”…Aromatic Rings.

Why do carbons form rings?
The Uniqueness of Carbon The carbon atom has four valence (outermost) electrons. Because each carbon is identical, they all have four valence electrons, so they can easily bond with other carbon atoms to form long chains or rings.
What are rings called in chemistry?
A molecule containing one or more rings is called a cyclic compound, and a molecule containing two or more rings (either in the same or different ring systems) is termed a polycyclic compound. A molecule containing no rings is called an acyclic or open-chain compound.
