    • Abstract

       

      The enthalpy of complex formation between different isomers of butylamine and butylalcohol was determined at 30°C by obtaining the partial molar enthalpy of dissociation of 1∶1 complexes inn-hexane. In both seriesviz. normal amine with isomeric alcohols and normal alcohol with isomeric amines, the enthalpy of complex formation showed the same trend ast>n>iso>sec.

      The trend in normal-normal, normal-tertiary, tertiary-tertiary and secondary-secondary omplexes was ast−n>n−n>t−t> sec-sec. Both these trends were explained in terms of steric and electromeric effects.
