  2. Cyclobutane - Wikipedia

    en.wikipedia.org/wiki/Cyclobutane

    Cyclobutane is a cycloalkane and organic compound with the formula (CH 2) 4. Cyclobutane is a colourless gas and is commercially available as a liquefied gas . Derivatives of cyclobutane are called cyclobutanes.

  3. Bent bond - Wikipedia

    en.wikipedia.org/wiki/Bent_bond

    Cyclobutane is a larger ring, but still has bent bonds. In this molecule, the carbon bond angles are 90° for the planar conformation and 88° for the puckered one. Unlike in cyclopropane, the C–C bond lengths actually increase rather than decrease; this is mainly due to 1,3-nonbonded steric repulsion.

  4. Cycloalkane - Wikipedia

    en.wikipedia.org/wiki/Cycloalkane

    Ball-and-stick model of cyclobutane In organic chemistry , the cycloalkanes (also called naphthenes , but distinct from naphthalene ) are the monocyclic saturated hydrocarbons . [ 1 ] In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring (possibly with side chains ), and all of ...

  5. Ladderane - Wikipedia

    en.wikipedia.org/wiki/Ladderane

    Simple ladderane structure. In chemistry, a ladderane is an organic molecule containing two or more fused cyclobutane rings. The name arises from the resemblance of a series of fused cyclobutane rings to a ladder. Numerous synthetic approaches have been developed for the synthesis of ladderane compounds of various lengths. [1]

  6. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    Acyclic aliphatic/non-aromatic compound Cyclic aliphatic/non-aromatic compound (cyclobutane)In organic chemistry, hydrocarbons (compounds composed solely of carbon and hydrogen) are divided into two classes: aromatic compounds and aliphatic compounds (/ ˌ æ l ɪ ˈ f æ t ɪ k /; G. aleiphar, fat, oil).

  7. Prismanes - Wikipedia

    en.wikipedia.org/wiki/Prismanes

    Chemically, it is a series of fused cyclobutane rings (a ladderane, with all-cis/all-syn geometry) that wraps around to join its ends and form a band, with cycloalkane edges. Their chemical formula is (C 2 H 2 ) n , where n is the number of cyclobutane sides (the size of the cycloalkane base), and that number also forms the basis for a system ...

  8. Pyrimidine dimer - Wikipedia

    en.wikipedia.org/wiki/Pyrimidine_dimer

    Cyclobutane dimer (CPD) (left), 6,4-dimer (6-4PP) (right) Pyrimidine dimers encompass several types, each with distinct structures and implications for DNA integrity. [citation needed] Cyclobutane pyrimidine dimer (CPD) is a dimer which features a four-membered ring formed by the fusion of two double-bonded carbons from adjacent pyrimidines.

  9. Cycloaddition - Wikipedia

    en.wikipedia.org/wiki/Cycloaddition

    This gives it the flexibility to engage in binding the double bonds as they undergo a cyclization reaction, generating a cyclobutane structure via C-C reductive elimination; alternatively a cyclobutene structure may be produced by beta-hydrogen elimination.
