CH3 A CH3 CHPCCH2CH3 Br CH3 A A CH3CHCCH2CH3 A Br Br2 Instead of trying to memorize twain equations, we move digit a general rule that bromine reacts with compounds that take in a CPC double bond to give the product think from addition crossways the double bond. This approach to understanding the chemical science of organic compounds presumes that certain atoms or gro ups of atoms known as operable groups give these compounds their characteristic properties. 1 2 FUNCTIONAL GROUP CHEMISTRY Functional groups stress attention on the alpha aspects of the structure of a molecule.

We fatiguet have to business organisation about the differences between the structures of 1-butene and 2-methyl-2-hexene, for example, when the compounds react with hydrogen bromide. We can center on on the fact that both compounds are alkenes that add HBr across the CPC double bond in the direction predicted by Markovnikovs rule, introduced in Section O1.8.
