Attaching a Methyl Group to Various Molecules

The term reaction is used to describe the process of bringing a methane molecule from infinity to a final position next to a hydrocarbon molecule, where the pair is replaced by a single hydrocarbon denoted by R-CH3. (Note that this is not a stoichiometric reaction in the usual sense.) 

Values of for the Interaction between Methane and Various Normal 

For a given group P (e.g., halogen or carboxylic or amino acid residue), one can study the HI as a function of the chain length n of the paraflSn 

A different study would be to fix n and examine the relative effects of different groups P on the solvent as they are revealed in the values of the HI.
