  2. Pentene - Wikipedia

    en.wikipedia.org/wiki/Pentene

    Pentenes are alkenes with the chemical formula C 5 H 10.Each molecule contains one double bond within its molecular structure. Six different compounds are in this class, differing from each other by whether the carbon atoms are attached linearly or in a branched structure and whether the double bond has a cis or trans form.

  5. 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 ...
