Before discussing the chemistry of alkyl E. halides, it should be pointed out that we wil g be talking primarily about compounds having halogen atoms bonded to saturated sp3-hybridized carbon. Other classes of organohalides, such as aromatic(aryl) and alkenyl(vinylic)halides, also exist, but much of their chemistry is different R一C-X Alkyl halide Aryl halide vinylic halideOrganic Chemistry Organic Chemistry Xiamen Xiamen University University Before discussing the chemistry of alkyl halides, it should be pointed out that we will be talking primarily about compounds having halogen atoms bonded to saturated, sp 3-hybridized carbon.
