Carboxylic Acids and Their Reactions
Start with the big picture
A central framework for understanding these reactions is nucleophilic acyl substitution: nucleophilic attack forms a tetrahedral intermediate, and the reaction depends on carbonyl electrophilicity and leaving-group ability. Comparing acyl derivatives helps explain their relative reactivity and the activation often needed for conversion. The topic connects this framework to acid chloride and anhydride formation, ester and amide synthesis, and intramolecular formation of lactones and lactams. It also introduces transformations with distinct outcomes, including decarboxylation of suitable substrates, reduction of carboxylic acids, the Hell–Volhard–Zelinsky reaction, and Kolbe electrolysis. Together, these ideas provide a way to relate reaction conditions, mechanisms, and products.
