The Thermodynamic Analysis of the Dispersive Interactions that Can Take Place between Different Solutes and High Molecular Weight n-Alkanes.
Adopting the procedure of dividing (DGo) into different parts so that the each portion represents the standard free energy associated with specific parts of a molecule, consider the distribution of the standard free energy throughout an n-alkane molecule. If a portion of (DGo) is allotted to each methylene group and also to the two methyl groups, then, algebraically, this can be expressed as follows.
RTLn(V'r(T))
= -nDGo(MethyleneGroup) -mDGo(Methyl Group)
| DGo(Methylene Group) | is standard free energy of the methylene group, | |
| DGo(Methyl Group) | is standard free energy of the methyl group, | |
| (n) | is the number of methylene groups, | |
| and, (m) | is the number of methyl groups (m=2 for an n-alkane). |
