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 ...

The number of possible isomers increases rapidly with the number of carbon atoms. For example, for acyclic alkanes: [3] C 1: methane only; C 2: ethane only; C 3: propane only; C 4: 2 isomers: butane and isobutane; C 5: 3 isomers: pentane, isopentane, and neopentane; C 6: 5 isomers: hexane, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane ...
These two isomers differ on which carbon the hydroxyl is bound to: either to an extremity of the carbon chain propan-1-ol (1-propanol, n-propyl alcohol, n-propanol; I) or to the middle carbon propan-2-ol (2-propanol, isopropyl alcohol, isopropanol; II).
Functional isomers are structural isomers which have different functional groups, resulting in significantly different chemical and physical properties. [ 11 ] An example is the pair propanal H 3 C–CH 2 –C(=O)-H and acetone H 3 C–C(=O)–CH 3 : the first has a –C(=O)H functional group, which makes it an aldehyde , whereas the second has ...
