Use the following atomic weights and quantities to calculate the overall % yield of dibenzyl ketone. Remember that your yield must be based on the limiting reagent, and that grams must be converted to moles. For problems not involving a one to one stoichiometry it may be easier to calculate the theoretical yield in grams from both reagents to determine which is truly the limiting reagent. Filling out most of the chart will help. Give only two significant digits in your answer. If after rounding the answer is a whole number, do not include a decimal point.

Refer to the following information to answer questions 1 to 9: As a biotechnologist working for a pharmaceutical company, you as tasked with preparing the cardiac antiarrhythmic agent Amelfolide from p-nitrobenzyl chloride and 2,6-dimethyl aniline (Figure 2.1). You are provided the starting materials and asked to prepare 7.50g of pure material. No other instructions are given to you. MW 2,6-dimethylaniline = 121.18 g/mol MW p-nitrobenzyl chloride = 185.56 g/mol MW Amelfoliode = 270.29 g/mol %3D NH2 CI O2N O2N When developing a synthetic scheme, the first thing to do is check the scientific literature to see if someone has done this reaction before you. Upon performing a literature search, you identify a publication where a group from Japan has performed the same reaction you are tasked with completing. The paper is in Japanese and you cannot read the details of the procedure, however, you can make out that the reaction is performed using DCM as the solvent and proceeds with a yield of…
