Organic Halides

Organic Halides are compounds of carbon and hydrogen in which one or more hydrogen atoms have been replaced by halogen atoms. They include Freon, Teflon, DDT, PCB and many other common products.

Naming Organic Halides 1. Name the parent hydrocarbon as usual. 2. Use prefixes chloro, bromo or iodo for chlorine, bromine and iodine groups respectively. 3. Use numbers and prefixes (di, tri etc) to indicate the position of the halogen groups

Name the following organic halides: 1. 2. 3.

Draw the structural diagram for the following: a. 1- bromo-3-chlorobenzene b. 2, 2, 5-tribromo-5-methylhexane

Properties of Organic Halides Halogens are more electronegative than carbon, therefore an organic halide is more polar than its’ parent hydrocarbon. This increased polarity increases intermolecular forces and therefore increases the boiling points of organic halides when compared to their corresponding hydrocarbon chains. It also increases their solubility in other polar solvents.
