The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1 ] [ 2 ] Number of C atoms
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The melting points of the alkanes follow a similar trend to boiling points for the same reason as outlined above. That is, (all other things being equal) the larger the molecule the higher the melting point. However, alkanes' melting points follow a more complex pattern, due to variations in the properties of their solid crystals. [a]
Higher alkanes are naturally present in crude oil and can be obtained via fractional distillation.Saturated fatty acids decarboxylate to higher alkanes. Long olefins can be hydrogenated to yield higher alkanes. n-alkanes can be isolated via the formation of urea clathrates.They can also be synthesized through Kolbe electrolysis or other coupling reactions like the Wurtz reaction.
Melting point: 16.8 to 10.0 °C; 62.1 to 49.9 °F; 289.9 to 283.1 K Boiling point: ... Pentadecane is an alkane hydrocarbon with the chemical formula C 15 H 32.
Melting point: 28 to 30 °C (82 to 86 °F; 301 to 303 K) ... Octadecane is distinguished by being the alkane with the lowest carbon number that is unambiguously solid ...
Melting point: 4 to 6 °C; 39 to 43 °F; 277 to 279 K Boiling point: ... Tetradecane is an alkane hydrocarbon with the chemical formula CH 3 (CH 2) 12 CH 3.
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 ...
