Quizplus · Accepted Answer

The reaction sequence involves the reduction of an aldehyde to a primary alcohol (I), followed by oxidation to a carboxylic acid (II), and finally treatment with PBr3 to convert the carboxylic acid to the corresponding acid chloride (III). The acid chloride then undergoes a nucleophilic substitution reaction with the amine, resulting in the formation of the amide product (IV). Therefore, the major product obtained from the reaction sequence is III, which is the acid chloride.
