Vedclass · Answer

(C) The thermal decomposition of dicarboxylic acids depends on the ring size of the resulting anhydride or ketone.For $n=0$ (oxalic acid) and $n=1$ (malonic acid),heating leads to decarboxylation,evolving $CO_2$ gas.For $n=2$ (succinic acid) and $n=3$ (glutaric acid),heating leads to the formation of stable cyclic anhydrides without the evolution of $CO_2$ gas.For $n \ge 4$,the formation of larger rings is less favorable,and other pathways may occur,but specifically for $n=2$,the product is succinic anhydride,which does not involve $CO_2$ loss.
