Abstract	A study of the relative rates of benzylic hydrogen abstractions from a series of meta and para substituted neopentylbenzenes by the bromine radical and trichloromethyl radical at 70°C has been carried out. Application of the Hammett equation yields p values of -0.75 for the bromine atom and -0.94 for the trichloromethyl radical. Steric hinderance in proceeding to the transition state is offered as a possible explanation for the large substituent dependence exhibited by the trichloromethyl radical.
