17.2 REACTIONS INVOLVING ALLYLIC AND BENZYLIC …
www.saplinglearning.com796 CHAPTER 17 • ALLYLIC AND BENZYLIC REACTIVITY when the reaction is promoted by heat, light, or free-radical initiators, an apolar solvent such as CCl 4 is used, and the bromine is added slowly so that its concentration remains very low. To summarize: Addition: (17.14a) Substitution: The effect of bromine concentration results from the rate laws for the competing reactions.

ncerthelp.comOH, Benzylic alcoho1(C 6 H 5 CH 2 OH) Structure of Alcohols and Phenols The oxygen atom of alcohols is Sp3 hybridised and they have tetrahedral position of hybrid atomic orbitals . The value of LROH bond angle depends upon the R group. For methyl alcohol, it is (∠C – O – H) 108.9° due to repulsion of lone pairs.
