There are other possibilities as well for this same molecular formula – for example, you could have a carbon-carbon double bond (an alkene) and an -OH group (an alcohol) in the same molecule.7) C 3 H 6 O. In this variety of structural isomerism, the isomers contain different functional groups - that is, they belong to different families of compounds (different homologous series). Remember, typical room temperature is about 25 °C. Identical compounds are not considered to be isomers. n-Pentane: The most straightforward structure of pentane is n-Pentane. Pentane has five carbon atoms that are arranged in a straight chain, and it exists in several different isomeric forms. Pentane means exclusively the n -pentane isomer; the other two being called isopentane (methylbutane) and neopentane (dimethylpropane).
