Haloalkanes nomenclature

In this chapter, we consolidate the nomenclature of a number of classes of compounds —an undertaking that may not seem very logical to someone who will soon be troubled enough with the chemistry of these compounds let alone their names. We recommend, however, a thorough study now of alkane and haloalkane nomenclature (Section 3-1) followed by a more cursory examination of the rest of the chapter. Then, as unfamiliar names arise, you can quickly review the basic rules for alkanes and proceed to the new class you have encountered. The idea is to have many of the important rules in one place. Nomenclature rules for other types of compounds are given in Chapter 7. 

Common names for simple haloalkanes are accepted by the IUPAC => alkyl halides (radicofunctional nomenclature). 

There are two ways of naming alkyl halides. The systematic (IUPAC) nomenclature treats an alkyl halide as an alkane with a halo- substituent Fluorine is fluoro-, chlorine is chloro-, bromine is bromo-, and iodine is iodo-. The result is a systematic haloalkane name, as in 1-chlorobutane or 2-bromopropane. Common or trivial names are constructed by naming the alkyl group and then the halide, as in isopropyl bromide. This is the origin of the term alkyl halide. Common names are useful only for simple alkyl halides, such as the following ... 

Common names for many simple haloalkanes are still widely used, however. In this common nomenclature system, called functional class nomenclature, haloalkanes are named as alkyl halides. (The following names are also accepted by the lUPAC.)... 

Compounds contsining a halogen atom covalently bonded to an sp hybridized carbon atom are named haloalkanes, or, in the common system of nomenclature, allindustrial solvents. In addition, haloalkanes are invaluable building blocks for organic synthesis because of the variety of ways in which the halogen may be substituted with other groups or eliminated to produce tt bonds.
