The reaction of phthalimide with sodium hypochlorite gets a product that had the molecular formula of C7H7NO2 (2-aminobenzoic acid specifically). Please answer the following based on the info given:
Reactions:Phthalic anhydride + urea --> phthalimide + CO2 + H2O
Phthalimide + NaOCl + NaOH + H+ --> C7H7NO2
A. What gas was responsible for the foaming when you acidified the reaction mixture? Write a balanced equation for the reaction thatliberated the gas.
B.When 35 mg of the product was mixed with 0.46 grams of camphor, the melting point of the mixture was found to be 157 degrees Celsius. Calculate the approximate molecular weight of the product if the melting point of pure camphor is 179 degrees Celsius and its freezing point depression constant is 40 degrees celsius * kg *mol-1. Also, show how the molecular formula C7H7NO2 can be derived using this result and basic information about the formation.
C. A problem occurred and the mixture was acidified to a pH of 2 with HCl and there was no precipitate. Explain what went wrong and write an equation for the reaction that caused the problem. How the product be recovered?
