  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. Cyclobutane itself is of no commercial or biological significance, but more complex derivatives are important in biology and ...

  3. 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 ...

  4. 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.

    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. Alkyl cycloalkane - Wikipedia

    en.wikipedia.org/wiki/Alkyl_cycloalkane

    The naming of polycyclic alkanes is more complex, with the base name indicating the number of carbons in the ring system, a prefix indicating the number of rings (e.g., "bicyclo"), and a numeric prefix before that indicating the number of carbons in each part of each ring, exclusive of vertices.

  8. Ring strain - Wikipedia

    en.wikipedia.org/wiki/Ring_strain

    The high strain energy of cyclobutane is primarily from angle strain. [7] cyclopentane (7.4 kcal/mol), C 5 H 10 — if it was a completely regular planar pentagon its bond angles would be 108°, but tetrahedral 109.5° bond angles are expected. [6] However, it has an unfixed puckered shape that undulates up and down. [6]

  9. 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.
