Rate studies for the solvolysis of several new ortho- and para-substituted benzhydryl bromides in 80percent aq. acetone have been conduced at two different temperatures.The carbophenoxy, 4-nitrocarbophenoxy, 4-chlorocarbophenoxy and 4-methylcarbophenoxy groups present at the ortho-position in benzhydryl bromide solvolyse faster than those present at the para-position.The results are further supported by the activation parameters evaluated for these compounds.A discussion of the various solvolysis mechanisms is presented in which it is proposed that the observed rate effects of these similarly constituted but electronically different substituents result from the variation in the nucleophilic capacity of these groups.
