| Abstract: | This paper,using the number N of carbon atoms and Wiener index W,P as structural parameters,established a quantitative relationship formula between boiling points and its molecular structure of alkane isomers.The boiling points of 76 branched chain alkanes were calculated.The results clearly showed that application of this formula is of very wide range with more accurate of its calculated results.The formula can be used to forecast the boiling points of alkane isomers. |

| Keywords: | alkane isomers boiling point structural parameter Wiener index |
