What would be the product(s) of this reaction if toluene replaced methyl benzoate? If only concentrated nitric acid were used in this reaction, will that increase the % yield of the reaction? And why? What is the function of concentrated sulfuric acid? Please use a reaction equation to show your answer. These are questions from my organic chemistry lab regarding the nitration of methyl benzoate to form m-nitrobenzoate through electrophilic aromatic substitution rxn.

What can cause a low percent yield? In lab we did fischer esterification using benzoic acid and methanol to yield methyl benzoate. 3.05 grams of benzoic acid were used and 1.10 grams of methyl benzoate were produced. We also washed the product multiple times with water, 10% sodium bicarbonate solution, then saturated sodium chloride solution. Could the washing cause a low percent yield? If so, can you explain why?
