11.3 Reactivity
The main idea is that the carboxyl group shows the chemistry of both the carbonyl (C=O) and the hydroxyl (-OH) groups. In most reactions, the carboxyl group is retained. However, the reactivity of these molecules is due to the presence of the carbonyl group. The carbonyl carbon is electron-defic
