| Abstract: | A new connectivity indes has been defined. The properties such as the standard enthalpies of formation, the standard entropies of alkanes were correlated with the connectivity indexes and the number of carbon atoms. The correlation coefficient is excellent, the calculated value of the two thermodynamic properties of alkanes are in excellent agreement with the experimental values. |

| Keywords: | connectivity indes regression coefficient alkanes thermodynamic property correlativity |
