n a pink aqueous solution of potassium permanganate, faintly addified with dilute sulfuric acid was treated the reaction took place with the evolution of gas bubbles, and the pink solution turned colorless. Further chemical analysis revealed that the evolved gas was oxygen, and the resulting solution contains potassium sulfate and manganese () sulfate; water was also formed during the same reaction.

2. Draw the structure of the byproduct that would be formed if the reaction mixture were not kept in an ice bath during the azo coupling reaction. [2 pts) Methyl orange can be synthesized using an azo coupling reaction, which is an example of an electrophilic aromatic substitution (EAS). In an azo coupling, the electrophile is an aryldiazonium salt, and the nucleophile is another electron-rich aromatic compound (typically an aniline or phenol). In this experiment, sulfanilic acid will be converted...

Reaction I is the first committed step in fatty acid synthesis, and reaction II is the first step in the conversion of pyruvate to glucose in gluconeogenesis. Both acetyl-CoA and pyruvate are carboxylated at the expense of ATP. What is the chemical logic behind this energy expenditure in both cases? For full marks, provide your answer with reaction schemes and electron pushing arrows.
