6 HOW ALKENES REAQ CURVED ARROWS SHOW THE FLOW OF ELECTRONS 

When you study the reactions of a particular functional group, you need to understand why the functional group reacts the way it does. It is not enough to look at the two reactions shown in Section 5.5 and see that the carbon-carbon double bond reacts with HBr to form a product in which the H and Br atoms have taken the place of the tt bond. You need to understand why the reaction occurs. If you understand the reason for each functional group s reactivity, you will reach the point where you can look at an organic compound and be able to predict the kind of reactions it will undergo. 

In essence, organic chemistry is all about the interaction between electron-rich atoms or molecules and electron-deficient atoms or molecules. These are the forces that make chemical reactions happen. So each time you encounter a new functional group, remember that the reactions it undergoes can be explained by a very simple mle  

Electron-deficient atoms or molecules are attracted to electron-rich atoms or molecules. 

Therefore, to understand how a functional group reacts, you must first learn to recognize electron-deficient and electron-rich atoms and molecules.
