Question

What would be the conclusion from all this data?

HWI. Using the same P2 reagent table data and the P3-P5 prompts from the REActivity, assess Student B's data and write a "conclusions" paragraph for your analysis. Feel free to show youe analysis on this paper. Please type your conclusion and attach it to the end of this document. он PCC CH2Cl2 rt, 30 min Student B: Crude data Crude mass: 1.lg white solid Crude mp: 60-62°C Crude yield: % Silica Gel Column (8:1 Hexanes: Ethyl acetate) Pure mass: 0.1g white solid Pure mp: 47-48°C Pure yield: % TLC: 4:1 hexanes: ethyl acetate (visualized by UV) sm = starting material co = cospot Rx = reaction smcorx sm cox @ 10 minutes @ 30 minutes

Answer 1

Conclusion =

Oxidation of alcohol to ketone carried out by using pridium chlorochromate. Here's confirmation of product and conclusion has to make on the basis of TLC.

By observing both TLC plate , it is confirm that reaction mass containing both product and reactant. Alcohol is converted into ketone with 50:50 ratio . because Co. Spot and Reaction mass spot Contains diphenyl-methanol and Benzophenone .Same conclusion can be drawn on the basis of IR , because IR spectra shows peak for OH and C=O group .

OH = stretching peak -3400-3600 cm^-1

C=O = stretching band for carbonyl group =1700cm^{-1 ,} but band not look so prominent because it has combination of mixture.
