Description
Complete a lab report for the following Fischer Esterification: The preparation of Methyl Benzoate.
This is submitted with a fully analyzed NMR spectrum. Please also put the following information:
Your name, Compound name, Weight of product in grams, Theoretical and percent yield calculations, Lab section number, Observations (conclusions).
1. Please show your calculations for obtaining your percent yield. Include the calculations for the theoretical yield as well. Also, if something went wrong during the course of your experiment (i.e you spilled your product, did the work-up wrong, etc.) you can explain it here. Include any modifications made in procedures, changes in colors during reaction or isolation, temperature increases, and report observed melting or boiling points.
2. Analyze your NMR spectra and upload a picture of it on this assignment. In your spectra, you should have the approximate chemical shifts of each peak. You also have to include an explanation matching up the peaks in your NMR spectra to that of the product, methyl benzoate. Explain why you think you got your product and not just starting material. If you have extra peaks in your NMR that do not match up to any proton peaks in your product, explain where they could have come from. Every peak must be accounted for!Attached are lab Manuel pages as well as results from personal experiment.

Fisher esterification - Synthesis of methyl benzoate
Introduction
The most common synthetic route to obtain ester comes from the interaction between a carboxylic
acid and an alcohol. It is a reversible process known as the Fisher esterification. In this reaction,
the starting materials react to form ester and water and it is usually catalyzed by a strong acid such
as sulfuric or phosphoric acid. The overall mechanism consists in the protonation of the carbonyl
group, followed by the nucleophilic attack of the alcohol to said carbon. Then, a proton transfer
converts the hydroxyl group into water, which leaves the molecule while the carbonyl double bond
is regenerated, leading to the ...
