  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. Butene - Wikipedia

    en.wikipedia.org/wiki/Butene

    In the chemical structures above, the small blue numbers in the structure images are the numbering of the atoms in the main backbone chain of the molecules. Other organic compounds have the formula C 4 H 8 , namely cyclobutane and methylcyclopropane , but are not alkenes and do not fall under the name butene .

  4. 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.

  5. 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.

  6. Cyclobutadiene - Wikipedia

    en.wikipedia.org/wiki/Cyclobutadiene

    The compound is the prototypical antiaromatic hydrocarbon with 4 pi electrons (or π electrons). It is the smallest [n]-annulene ([4]-annulene).Its rectangular structure is the result of a pseudo [3] - (or second order) Jahn–Teller effect, which distorts the molecule and lowers its symmetry, converting the triplet to a singlet ground state. [4]

  8. 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]

  9. 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.
