Cyclo - octasulfuran 8-membered inorganic cyclic compound non-aromatic. Substitution of one or more of the ring carbon atoms in the molecules of a carbocyclic compound with a heteroatom gives a heterocyclic compound. A functional group or other substituent that is aromatic is called an aryl group. Benzene is a more stable molecule than would be expected without accounting for charge delocalization. Load Previous Page. Macrocycles can access a number of stable conformationswith preference to reside in conformations that minimize transannular nonbonded interactions within the ring e. The following are examples of cyclic compounds exhibiting more complex ring systems and stereochemical features:. Clark; Galynker, Igor

A cyclic compound ring compound is a term for a compound in the field of chemistry in which one or more series of atoms in the compound is connected to form a ring.
The following are examples of simple and aromatic carbocycles, inorganic cyclic compounds, and heterocycles:. Note, elsewhere an organic chemistry shorthand is used where hydrogen atoms are inferred as present to fill the carbon's valence of 4 rather than their being shown explicitly.
Examples include sulfursilicon e.
For example, the following scenario is presented in Ref. Homocyclic compounds are also known as carbocyclic compounds. Note: There are,however, examples of aromatic compounds which do not contain a. Carbocyclic compounds are extremely widespread, and many of them are of great practical importance.

Heterocyclic compound Comparison with carbocyclic compounds
Benzenea 6-membered carbocyclic compound. Hence, if forced into the higher energy boat form, these methyl groups are in steric contact, repel one another, and drive the equilibrium toward the chair conformation. Rings may vary in size from three to many atoms, and include examples where all the atoms are carbon i.

Carbocyclic compound Definition of Carbocyclic compound at
Depending on ring size, the three-dimensional shapes of particular cyclic structures—typically rings of 5-atoms and larger—can vary and interconvert such that conformational isomerism is displayed.
Homocyclic or Carbocyclic Compounds

In compounds with maximum unsaturation, if the double bonds can be arranged in more than one way, their positions are defined by indicating the nitrogen or carbon atoms that are not multiply bonded and that consequently carry an extra hydrogen atom or substituentas follows: 1 H - 2 H - and so on.

Examples include sulfursilicon e. In organic chemistry, a variety of synthetic procures are particularly useful in closing carbocyclic and other rings; these are termed ring-closing reactions. Moreover, the closing of atoms into rings may lock particular functional group — substituted atoms into place, resulting in stereochemistry and chirality being associated with the compound, including some manifestations that are unique to rings e.
Nonaromatic unsaturated compounds are highly reactive—that is, they readily undergo additions of atoms or groups of atoms to the carbon atoms of their double bonds, giving each carbon four substituents.

They are classified as unsaturated if they contain a double or triple bond between any two of the carbon atoms, and they are classed as aromatic if they contain at least one ring, all atoms of which are joined by alternating double and single bonds.
A cyclic compound ring compound is a term for a compound in the field of chemistry in which one or more series of atoms in the compound is connected to form a ring. The molecules of organic chemical compounds are built up from a framework or backbone of carbon atoms to which are attached hydrogen Hoxygen, or other heteroatoms. For instance, cyclohexanes —six membered carbocycles with no double bonds, to which various substituents might be attached, see image—display an equilibrium between two conformations, the chair and the boat, as shown in the image. H; Nogales, E Thus, pyrrolidine may be considered as a cyclic secondary amine and has much in common with the corresponding acyclic amine, diethylamine, which is represented by the formula:. |
IUPAC nomenclature has extensive rules to cover the naming of cyclic structures, both as core structures, and as substituents appended to alicyclic structures. Perspectives in Structural Chemistry Edited by J.
