r values suggest the operation of the kc mechanism in this solvolysis without nucleophilic solvent assistance and methyl participation. From a comparison of the substituent effects, the exalted r value of 1.15 observed in the solvolysis of α-methylbenzyl chlorides can be attributed to the enhanced resonance demand characteristic of secondary benzylic system rather than to a correlational artifact arising
