  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

    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 ...

  6. Cyclobutanol - Wikipedia

    en.wikipedia.org/wiki/Cyclobutanol

    Cyclobutanol is an organic compound with the chemical formula C 4 H 8 O; it is defined as a cyclobutyl group with a hydroxyl group pendant and thus a cycloalkanol. Physically, it is a yellowish clear liquid [1] that crystallizes orthorhombically at low-temperatures.

  7. 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]

  8. Compliance constants - Wikipedia

    en.wikipedia.org/wiki/Compliance_constants

    Note that it is known that the all the four equivalent C-C bonds in cyclobutane are weaker than any of the two distinct C-C bonds in n-butane; [13] therefore, juxtaposition and evaluation of the strength of the C-C bonds in this C4 system can exemplify how force constants fail and how compliance constants do not.

  9. Pyrimidine dimer - Wikipedia

    en.wikipedia.org/wiki/Pyrimidine_dimer

    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. CPDs disrupt the formation of the base pair during DNA replication, potentially leading to mutations. [8] [9] [10]
