  2. Cyclopentane - Wikipedia

    en.wikipedia.org/wiki/Cyclopentane

    Its freezing point is −94 °C and its boiling point is 49 °C. Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more carbon rings. It is formed by cracking cyclohexane in the presence of alumina at a high temperature and pressure. It was first prepared in 1893 by the German chemist Johannes Wislicenus. [5]

    It is a saturated cyclopentane with three methyl substituents branching off carbons 1,2, and 3. The methyl groups off carbons 1 and 3 are trans with respect to each other, while the methyl group off carbon 2 has undefined stereochemistry , allowing it to be either cis or trans with respect to methyl 1 or 3.

  8. Pentane - Wikipedia

    en.wikipedia.org/wiki/Pentane

    Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
