  2. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...

  3. 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]

  4. Cycloalkyne - Wikipedia

    en.wikipedia.org/wiki/Cycloalkyne

    Cycloalkynes have a general formula C n H 2n−4. Because of the linear nature of the C−C≡C−C alkyne unit, cycloalkynes can be highly strained and can only exist when the number of carbon atoms in the ring is great enough to provide the flexibility necessary to accommodate this geometry .

  5. Heterocyclic compound - Wikipedia

    en.wikipedia.org/wiki/Heterocyclic_compound

    A large group of 5-membered ring compounds with three or more heteroatoms also exists. One example is the class of dithiazoles , which contain two sulfur atoms and one nitrogen atom. Five-membered rings with one heteroatom

  6. Cycloalkane - Wikipedia

    en.wikipedia.org/wiki/Cycloalkane

    Norbornane (also called bicyclo[2.2.1]heptane). 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.

  7. IUPAC nomenclature of organic chemistry - Wikipedia

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

    If the alkyl group is not attached at the end of the chain, the bond position to the ester group is suffixed before "-yl": CH 3 CH 2 CH(CH 3)OOCCH 2 CH 3 may be called butan-2-yl propanoate or butan-2-yl propionate. [citation needed]. The prefix form is "oxycarbonyl-" with the (R') group preceding.

  8. Bicyclic molecule - Wikipedia

    en.wikipedia.org/wiki/Bicyclic_molecule

    The bridged bicyclic norbornane, formally bicyclo[2.2.1]heptane The spirocyclic compound spiro[5.5]undecane DABCO (1,4-diazabicyclo[2.2.2]octane) is often incorrectly depicted with one skewed ethylene group for the sake of clarity. A bicyclic molecule (from bi 'two' and cycle 'ring') is a molecule that features two joined rings. [1]

  9. Cycloalkylamine - Wikipedia

    en.wikipedia.org/wiki/Cycloalkylamine

    Cycloalkylamines are chemical compounds featuring a cycloalkyl group and an amine. [1] Some examples include propylhexedrine, cyclopentamine, cypenamine, and tranylcypromine. Some chemicals act as stimulants. [2]
