  2. Cyclopentane - Wikipedia

    en.wikipedia.org/wiki/Cyclopentane

    Cyclopentane is also used in the manufacture of synthetic resins and rubber adhesives. [citation needed] Cyclopentane is a minor component of automobile fuel, with its share in US gasoline varying between 0.2 and 1.6% in early 1990s [8] and 0.1 to 1.7% in 2011. [9] Its research and motor octane numbers are reported as 101 or 103 and 85 or 86 ...

  4. Alicyclic compound - Wikipedia

    en.wikipedia.org/wiki/Alicyclic_compound

    An exocyclic group is always shown outside the ring structure, take for instance the exocyclic double bond of the former molecule. Isotoluenes are a prominent class of compounds with exocyclic double bonds. The placement of double bonds in many alicyclic compounds can be predicted with Bredt's rule.

  5. Heterocyclic compound - Wikipedia

    en.wikipedia.org/wiki/Heterocyclic_compound

    A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). [1] Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles .

  6. Gonane - Wikipedia

    en.wikipedia.org/wiki/Gonane

    Gonane is a significant chemical compound in the family of steroids because its structure comprises four hydrocarbon rings fused together, consisting of three cyclohexane units and one cyclopentane, which is often referred to as the "steroid nucleus" and serves as the parent compound for steroids.

  7. Methylcyclopentane - Wikipedia

    en.wikipedia.org/wiki/Methylcyclopentane

    The C 6 core of methylcyclopentane is not perfectly planar and can pucker to alleviate stress in its structure. [7] The conversion of methylcyclopentane to benzene is a classic aromatization reaction, specifically a dehydroisomerization. This platinum (Pt)-catalyzed process is practiced on scale in the production of gasoline from petroleum.

  8. List of refrigerants - Wikipedia

    en.wikipedia.org/wiki/List_of_refrigerants

    According to ASHRAE standard 34, the R-number of a chemical refrigerant is assigned systematically according to its molecular structure and has between two and four digits. If there are carbon -carbon multiple bonds , there are four digits in all: the number of these bonds is the first digit and the number of carbon atoms minus one (C-1) is next.
