Alkyl Halides Classification Methyl halides:Halide is attached to a methyl group. Primary alkyl halide:Carbon to which halogen is bonded is attached to only one other carbon. Secondary alkyl halide:Carbon to which halogen is bonded is attached to two other carbons. Tertiary alkyl halide:Carbon to which halogen is bonded is attached to three other carbons. 2013 Pearson Education Inc. 9
