An erlenmeyer flask is charged with 3-nitrobenzamide. A 1 M sodium hydroxide solution and household bleach are added to the flask with stirring. The mixture was heated in a hot water bath at 80 degrees Celsius for 30 mins. The flask was removed from the water bath and cooled to 50 degrees Celsius and then a 10% aqueous NaHSO3 solution was added to the flask. The solution was cooled in an ice bath and collected by filtration with a Hirsch funnel. Recrystallization from 95% ethanol gave yellow crystals. What is the overall mechanism for this reaction including all arrows, the identification of the electrophile and nucleophile, and all charges?
