  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. 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. Prismanes - Wikipedia

    en.wikipedia.org/wiki/Prismanes

    The prismanes are a class of hydrocarbon compounds consisting of prism-like polyhedra of various numbers of sides on the polygonal base. 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.

  6. Cyclobutanone - Wikipedia

    en.wikipedia.org/wiki/Cyclobutanone

    Kischner synthesized cyclobutanone from cyclobutanecarboxylic acid. The Russian chemist Nikolai Kischner first prepared cyclobutanone in a low yield from cyclobutanecarboxylic acid.

  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. 2-Butyne - Wikipedia

    en.wikipedia.org/wiki/2-butyne

    2-Butyne (dimethylacetylene, crotonylene or but-2-yne) is an alkyne with chemical formula CH 3 C≡CCH 3.Produced artificially, it is a colorless, volatile, pungent liquid at standard temperature and pressure.

  9. Cyclopropanation - Wikipedia

    en.wikipedia.org/wiki/Cyclopropanation

    In organic chemistry, cyclopropanation refers to any chemical process which generates cyclopropane ((CH 2) 3) rings.It is an important process in modern chemistry as many useful compounds bear this motif; for example pyrethroid insecticides and a number of quinolone antibiotics (ciprofloxacin, sparfloxacin, etc.).
