  2. Neopentane - Wikipedia

    en.wikipedia.org/wiki/Neopentane

    Neopentane is a flammable gas at room temperature and pressure which can condense into a highly volatile liquid on a cold day, in an ice bath, or when compressed to a higher pressure. Neopentane is the simplest alkane with a quaternary carbon, and has achiral tetrahedral symmetry.

    en.wikipedia.org/wiki/Quaternary_carbon

    Structural formula of neopentane (quaternary carbon is highlighted red) A quaternary carbon is a carbon atom bound to four other carbon atoms. [ 1 ] For this reason, quaternary carbon atoms are found only in hydrocarbons having at least five carbon atoms.

  4. 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 ...

  5. Isopentane - Wikipedia
