Understanding Phenols and Aryl Halides UniversalClass

Understanding Phenols And Aryl Halides Universalclass

Characteristics of Aryl Halides and Phenols . Aryl halides are in many ways similar to alkyl halides. One of the major differences is the sp 2 hybridization of the carbon atoms in the benzene ring, which makes the carbon atom bound to the halogen more electronegative in the case of an aryl halide versus and alkyl halide. Phenols, because of the hydroxyl group, can form hydrogen bonds.
