In biochemical reactions, decarboxylation of carboxylic acids typically takes place for-keto carboxylic acids. Justify a rational why nature opted for-keto carboxylic acid decarboxylation. Among the following types of biochemical reactions, ester hydrolysis, rearrangement reactions, water elimination reactions, and anhydride hydrolyses, which one is the most favorable one. Rank the above reactions types in the order of being the most to least favorable reaction

Draw the structures of the products from the hydrolysis of each of the following with NaOHNaOH.
