N-pentane (Product name: Pentane), chemical formula C5H12, the fifth member of the alkane. There are two isomers of n-pentane: isopentane (boiling point 28 ° C) and neopentane (boiling point 10 ° C). The term "pentane" usually refers to n-pentane, which is its linear isomer. . Alkanes were first named using customary nomenclature. However, this nomenclature is difficult to use for alkanes with many carbon numbers and many isomers. So someone proposed a nomenclature for derivation, treating all alkanes as derivatives of methane, such as isobutane called 2-methylpropane.
