Carboxylic acid – Synthesis of carboxylic acids: Most of the methods for the synthesis of carboxylic acids can be put into one of two categories: (1) hydrolysis of acid derivatives and (2) oxidation of various compounds. All acid derivatives can be hydrolyzed (cleaved by water) to yield carboxylic acids; the conditions required range from mild to severe, depending on the compound involved.

Because Mg(OH) 2 is listed in Table 12.2 “Strong Acids and Bases”, it is a strong base. The nitrogen in C 5 H 5 N would act as a proton acceptor and therefore can be considered a base, but because it does not contain an OH compound, it cannot be considered a strong base; it is a weak base. Test Yourself. Identify each acid or base as strong.
