The free radical chlorination products of several alkyl aromatic compounds containing primary, secondary, and tertiary hydrogens have been investigated and the relative reactivity ratios for the various hydrogens are reported. Sulfuryl chloride was used as the source for the chlorine radicals, and AIBN as the radical initiator. The final objective is to obtain the relative reactivity ratios for 3o:2o:1o benzylic hydrogens and compare them to the corresponding ratios of aliphatic 3o:2o:1o. The relative reactivity ratios for primary, secondary, and tertiary allylic hydrogens is also under investigation.
