Document Summary
Chm 255 - lecture 24 - alkyl halides. When naming alkyl halides the same rules apply as for naming alkanes, alkenes, and alkynes. Use a prefix describing which halogen is present on the molecule (bromo for bromine, chloro for chlorine, etc. ) The prefix describing the the halogen is preceded by the number of the carbon it is attached to. Alkyl halides can be produced from the addition of hx or x2 to alkenes (x being a halogen) Alkanes can also form alkyl halides through reactions involving radicals. Heterolytic bond cleavage - when a bond splits and both electrons in the bonding pair goes to one atom, creating a cation and an anion. Homolytic bond cleavage - when a bond splits and each atom in the bond receives one electron from the bonding pair, resulting in two radicals. The flow of one electron as in the formation of radicals is indicated by curved.
