Rates of reaction in nitrobenzene solution of methyl iodide with pyridine, quinoline, isoquinoline, 2-methylquinoline and 8-methylquinoline have been followed over the temperature range 10-50", using a precise conductimetric method. Relative heats of activation have been taken as quantitative measures of steric strains present in the activated complexes of these reactions. From these results, an estimate is made of the steric strains ...
