Can boiling range alone be used to confirm the identity of the product during fischer esterification?
no ,not only boiling range can confirm the identity of product during fischer esterification
the tool to confirm product identity is boiling point,density,refractive index,NMR,and mass spectrometry
Can boiling range alone be used to confirm the identity of the product during fischer esterification?
DATA: amount of product collected = 1.727 g boiling range: 130–135 ° QUESTIONS Was the reaction successful? What was the actual yield? (You may need to do some unit conversions for this) Comment on the boiling range. Can boiling range alone be used to confirm the identity of the product? Does the IR spectrum show expected signals for the ester? Point to specific stretches that are present in the product but not in the reactants. Please answer and explain! %Transmittance...

in synthesizing ethyl acetate by fischer esterification a Vernier Mini GC will be used. the GC uses a metal column with a nonpolar coating and atmospheric air as the mobile phase, in addition, the temperature of the GC can be varied. under these conditions, what component will show up first in your chromatogram? ethyl, acetic acid or ethyl acetate?

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?
