Document Summary

Chemistry 2213a fall 2012 western university. Like hydrogen, the halogens have a valence of one. So, a halogen atom can replace a hydrogen atom in a molecule, so the general formula of a saturated mono-halo acyclic compound is cnh2n+1x. Therefore, treat x as an h when calculating unsaturation units. e. g. c3h4br2 = one unit of unsaturation. Non-iupac, two-word names are commonly used for simple compounds. The first word identifies the alkyl group, the second identifies the halogen. bromocyclohexane. Clbr the reactions that alkyl halides undergo strongly depend on the nature of the alkyl position. It"s essential that we recognize the type of alkyl halide. The carbon bearing the halogen is bonded to one alkyl group and has two h: secondary halide (2 ). The carbon bearing the halogen is bonded to two alkyl groups and one h: tertiary halide (3 ). The carbon bearing the halogen is bonded to three alkyl groups and no h.
