A total of 29 new calorimetrically measured values for the enthalpies of solution of 2-bromo-2-methylpropane and 2-bromo-2-methylbutane in mono- and dialcohols at 298.15 K is presented. The solution enthalpies were combined with the enthalpies of vaporization of the solutes to yield the solvation enthalpies. The values are sensitive to the solvent structure and the size of the alkyl halide. Particular attention was given to the change of the hydrocarbon chain (CH3 --> C2H5) and the halide (Cl --> Br) in the solute molecule.
