CH3 A CH3 CHPCCH2CH3 Br CH3 A A CH3CHCCH2CH3 A Br Br2 Instead of trying to memorize twain equations, we move reach a general rule that bromine reacts with compounds that take in a CPC double bond to give the product suppose from addition across the double bond. This approach to understanding the chemistry of organic compounds presumes that certain atoms or groups of atoms known as structural groups give these compounds their characteristic properties. 1 2 FUNCTIONAL GROUP CHEMISTRY Functional groups stress attention on the pregnant aspects of the structure of a molecule.
We fatiguet have to wish 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 focus 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.
