Document Summary

Chapter 10: the chemistry of the alkyl halides. Alkyl halide a compound containing a halogen atom covalently bonded to an sp3 hybridized carbon atom. Halogen substituents are indicated by the prefixes fluoro-, chloro-, bromo-, and iodo- and listed in alphabetical order with other substituents. Halogens increase in size going down the periodic table lengths of corresponding c-h bonds increase accordingly. C-x bond strengths decrease going down the periodic table. C-x bond is polar; c +, x : results in dipole moment for all halomethanes. Implies that the alkyl halide c-x carbon atom should behave as an electrophile in polar reactions. 10. 2 preparing alkyl halides from alkanes: radical halogenation. 10. 3 preparing alkyl halides from alkenes: allylic bromination. 10. 4 stability of the allyl radical: resonance revisited. 10. 5 preparing alkyl halides from alcohol (and alkene) Preparation of alkyl halides: reaction of alkenes with hx or x2, from alcohols. A common approach for primary and secondary alcohols.
