%X a quantitative analysis is made on the correlation ship of thermodynamic property, i.e., standard enthalpy of formation (¦Äh fo) with kier's molecular connectivity index(1xv),vander waal's volume (vw) electrotopological state index (e) and refractotopological state index (r) in gaseous state of alkanes. the regression analysis reveals a significant linear correlation of standard enthalpy of formation (¦Äh fo) with 1xv, vw, e and r. the equations obtained by regression analysis may be used to estimate standard enthalpy of formation (¦Äh fo) of alkanes in gaseous state.
