These papers contain 4 different molecular formulas. The pages are numbered 1-4 representing the 4 compounds.

Please determine and draw the unknown compound for the pages labeled "1." Please also assign the peaks for the relevant NMR and IR of "1." Annotate these peaks directly on the corresponding picture and label each peak (e.g. "1,2,3... or a,b,c" etc.)

If the peaks are not labeled, the problem will be considered incomplete.
