Why might the OH stretch in the IR of MY triphenylmethanol product be less intense than expected when compared to the expected IR for triphenylmethanol? However, NIST makes no warranties to that effect, and NIST
PDF Experiment 36A, Triphenylmethanol; Report United States Ask an Expert. In this case, the electrons on the negatively charged oxygen atom are used to reform the carbonyl pi bond, thereby forcing the C-N or C-O bond of the ester, amide, or anhydride to detach as a leaving group generating a ketone intermediate. The melting point of the product was then determined and recorded. However, some of the other peaks are also somewhat decreased in intensity so it is a possibility.

Working time, When you receive an IRS audit it can be a scary event and it is difficult to find out what you should do next. Also, IR spectroscopy was used to make additional observations about the products by using a KBr pellet. Absorption Description | Experimental, Premium Magnesium ANY clues why my triphenylmethanol (OH stretch) is not as intense? It is recommended to provide more analysis for each signal than what is described above, when necessary, such as labeling any coupling constants if any are provided.
