You have already encountered alkyl halides several times in this course. In this chapter, you will examine in some detail the methods that are used to prepare these important compounds. For chemists involved in the synthesis of new organic compounds, alkyl halides are extremely useful, particularly because of their ability to react with certain metals and form organometallic compounds. However, a detailed discussion of the reactions of alkyl halides will be delayed until Chapter 11.
- 10.7: Preparing Alkyl Halides from Alcohols
- This page looks at reactions in which the -OH group in an alcohol is replaced by a halogen such as chlorine or bromine. It includes a simple test for an -OH group using phosphorus(V) chloride.
- 10.10: Oxidation and Reduction in Organic Chemistry
- In organic chemistry, redox reactions look a little different. Electrons in an organic redox reaction often are transferred in the form of a hydride ion - a proton and two electrons. Because they occur in conjunction with the transfer of a proton, these are commonly referred to as hydrogenation and dehydrogenation reactions: a hydride plus a proton adds up to a hydrogen (H2) molecule. Be careful - do not confuse the terms hydrogenation and dehydrogenation with hydration and dehydration.
