Organic Chemistry II Lab Assignment
0.78 g of p-bromobenzaldehyde is mixed with 6.0 mL of ethanol and 3.0 mL of 2.0 M NaOH. To this solution, with stirring, is added 0.30 g of 1,3-diphenylacetone. The reaction is heated and the crude product is collected by filtration.
-Write a balanced structure equation for this reaction, including a prediction of the product structure.
-Determine the limiting reactant and theoretical yield, clearly showing your work and stating your assumptions.
-Calculate the chemical shift of any vinylic protons in the product, using the appropriate table from the techniques book (also found in the spectra assignments handout). Show your work, including what substituent parameters you chose to use.
You have been given the C-13 and DEPT 135° NMR spectra of an unknown alcohol with formula C5H11OH or C6H13OH The summary of the data from those spectra are:
The most downfield peak, which is found just upfield from the solvent peak (CDCl3), has an upward-pointing peak correlated in the DEPT-135° spectrum.
There are five additional peaks (for a total of 6) in the carbon spectrum, only one of which points downward in the DEPT 135°.
List all the possible structures for this unknown. Organic Chemistry II Lab Assignment
