'''Heptadecane''' is an [[organic compound]], an [[alkane]] [[hydrocarbon]] with the [[chemical formula]] C<sub>17</sub>H<sub>36</sub>. The name may refer to any of 24894 theoretically possible [[structural isomer]]s, or to a mixture thereof.

The unbranched isomer is '''normal''' or '''''n''-heptadecane''',  CH<sub>3</sub>(CH<sub>2</sub>)<sub>15</sub>CH<sub>3</sub>.  In the IUPAC nomenclature, the name of this compound is simply '''heptadecane''', since the other isomers are viewed and named as [[alkyl]]-substituted versions of smaller alkanes.

The most compact and branched isomer would be [[tetra-tert-butylmethane|tetra-''tert''-butylmethane]], but its existence is believed to be impossible due to [[steric hindrance]]. Indeed, it is believed to be the smallest "impossible" alkane.<ref name="silva">{{Cite journal | author = K. M. de Silva and J. M.
