Relationship between Topological Indices and Thermodynamic Properties and of the Monocarboxylic Acids Applications in QSPR

Topological indices are the numerical value associated with chemical constitution purporting for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. Graph theory is a delightful playground for the exploration of proof techniques in Discrete Mathematics and its results have applications in many areas of sciences. One of the useful indices for examination of structureproperty relationship is Randic' index. In this study is represented the relationship between the Randic', Balaban and Szeged indices and Harary numbers to the enthalpies of combustion (  C H  liquid), enthalpies of vaporization (  vap H  gas), enthalpies of formation (  f H  liquid) and enthalpies of sublimation (  sub H  ) of monocarboxylic acids (C2C20) are established, and then, some useful topological indices for examination of the structureproperty relationship are presented.
