  2. Cycloalkane - Wikipedia

    en.wikipedia.org/wiki/Cycloalkane

    Unsubstituted cycloalkanes that contain a single ring in their molecular structure are typically named by adding the prefix "cyclo" to the name of the corresponding linear alkane with the same number of carbon atoms in its chain as the cycloalkane has in its ring. For example, the name of cyclopropane (C 3 H 6) containing a three-membered ring ...

  3. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    Cycloalkanes and aromatic compounds can be treated as the main parent chain of the compound, in which case the positions of substituents are numbered around the ring structure. For example, the three isomers of xylene CH 3 C 6 H 4 CH 3 , commonly the ortho- , meta- , and para- forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4 ...

  4. Cyclic compound - Wikipedia

    en.wikipedia.org/wiki/Cyclic_compound

    IUPAC nomenclature has extensive rules to cover the naming of cyclic structures, both as core structures, and as substituents appended to alicyclic structures. [citation needed] The term macrocycle is used when a ring-containing compound has a ring of 12 or more atoms. [6] [7] The term polycyclic is used when more than one ring appears in a ...

  5. Bicyclic molecule - Wikipedia

    en.wikipedia.org/wiki/Bicyclic_molecule

    Bicyclic molecules are described by IUPAC nomenclature. [6] [7] [8] The root of the compound name depends on the total number of atoms in all rings together, possibly followed by a suffix denoting the functional group with the highest priority. Numbering of the carbon chain always begins at one bridgehead atom (where the rings meet) and follows ...

  6. Spiro compound - Wikipedia

    en.wikipedia.org/wiki/Spiro_compound

    A spiro compound, or spirane, from the Latin spīra, meaning a twist or coil, [22] [5]: 1138 [23] is a chemical compound, typically an organic compound, that presents a twisted structure of two or more rings (a ring system), in which 2 or 3 rings are linked together by one common atom, [2]: SP-0

  7. Alkyl cycloalkane - Wikipedia

    en.wikipedia.org/wiki/Alkyl_cycloalkane

    Alkyl cycloalkanes are chemical compounds with an alkyl group with a single ring of carbons to which hydrogens are attached according to the formula C n H 2n . They are named analogously to their normal alkane counterpart of the same carbon count: methylcyclopropane , methylcyclobutane , methylcyclopentane , methylcyclohexane , etc. [ 1 ]

  8. Substituent - Wikipedia

    en.wikipedia.org/wiki/Substituent

    In organic chemistry, a substituent is one or a group of atoms that replaces (one or more) atoms, thereby becoming a moiety in the resultant (new) molecule. [1] ( In organic chemistry and biochemistry, the terms substituent and functional group, as well as side chain and pendant group, are used almost interchangeably to describe those branches from the parent structure, [2] though certain ...

  9. Ring (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Ring_(chemistry)

    Four cycloalkanes, all of which exhibit simple rings. In chemistry, a ring is an ambiguous term referring either to a simple cycle of atoms and bonds in a molecule or to a connected set of atoms and bonds in which every atom and bond is a member of a cycle (also called a ring system).
