Question
The progress of a chemical reaction may often be followed spectroscopically by removing a small aliquot of the reaction mixture at periodic intervals and running its spectrum. Describe how you could follow the progress of the elimination of the dibromo acid (below) using IR and^1H NMR spectroscopy. Specifically, fill in the following table to identify the peak(s) in the spectrum you would expect to appear, disappear, or change position as the organic reactant is converted into product. Give approximate positions of peaks in cm^-1 (IR) and ppm (^1H NMR). In order to ensure that the reaction goes to completion, the starting materials were refluxed for an extended period and then heated again during the evaporation of the solvent. Based on your proposed mechanism, what is the likely intermediate product that could form if the elimination reaction does not run to completion? If this intermediate product was present in your final product, what evidence would have that your final product was contaminated?Explanation / Answer
Using pellet method we can perform IR, The reaction conversion into n number of products will be possible. Moreover the structural identification is possible by NMR.
The dibromide molocules undergoes acid and base hydrolysis it releases the intermediate by using sulphurc acid and Potassium hydroxide. the structure can be identified by NMR.
