Question

2. For the reaction below: a. Predict the most stable product(s) and draw the mechanism Br OK b. Redraw the product/s) below and label all the non-equivalent carbons. How many sonals would you expect to see in the C NMR of the product? Predict the chemical shifts of each carbon below. c. Redraw the product(s) below and label all the non-equivalent hydrogens. How many signals would you expect to see in the 'H NMR of the product? Predict the chemical shifts of each hydrogen below. 3. Predict the 'H NMR spectrum of the molecule shown to the left. Be sure to include the x-axis for the 'H NMR spectrum labelled with units, peaks for each of the non-equivalent protons clearly showing the expected splitting patterns, approximate chemical shifts, and integration HO
