Vedclass · Answer

(A) The starting material is cyclohexane$-1,1,2-$tricarboxylic acid. Upon heating,the geminal dicarboxylic acid group undergoes decarboxylation (loss of $CO_2$) to form cyclohexane$-1,2-$dicarboxylic acid. The resulting cyclohexane$-1,2-$dicarboxylic acid has the two carboxylic acid groups in a $cis$ configuration relative to the ring. Further heating leads to the loss of a water molecule (dehydration) between the two adjacent carboxylic acid groups to form a cyclic anhydride. Since the starting configuration is $cis$,the product formed is $cis-$cyclohexane$-1,2-$dicarboxylic anhydride.
