YOUR Name: Lab room: Partner Name: Lab time: TA Name: Hood #: Give brief, 1-2 sentence responses to the following questions 1 (3 pts). What is the solvent, what is the reagent and what is the reactant you will use in your synthesis of acetaminophen? Solvent = Reagent = Reactant 2 (1 pt). What two steps will be used to first isolate the product of the reaction? 3 (1 pt). What procedure will be used to purify the product? 4 (1 pt). How will you calculate the theoretical yield? 5 (1 pt). How will you calculate the chemical yield? 6 (1 pt). What is the purpose of refluxing your reaction? 7 (1 pt). Will you determine the limiting reagent by comparing weights or moles? 8 (1 pt). Give one of the two ways you will characterize your product?

Answer 1

Date: Subject solvent - De lonised Water Reagent = Acetic Anhydride Reactant = 4-Aminophenol Crystalline product first filtered by Büchner funnel. wash crude product with cold water 3. Recrystallisation of acetaminophen of product in with solvent saturated solution methanoll chot) Theoretical yield - Xloo Molar mass of P-Aminophenol Molar mass of Acclaminophen chemical yield - The Actual yield x 100 Theoretical yield 6 main rate in purpose of Refluxing of Reaction and dimit time. Rxn is completion to of increase Reaction 7. No, Here limiting is or weight. Here can not determine by moles. limiting Reagent is 4-Aminophenol. a) FTIR 6). N.M.R
