please analyze the peaks and determine the unknown compound. possible unknowns: acetanilide, benzoin, vanillin, ortho-toluic acid, benzamide,benzoic acid, 4-hydroxyacetophenone, 4-hydroxybenzaldehyde, or 3-nitrobenzoic acid. my unknown code is mercurcy

1. Clearly identify and label the characteristic peaks on the spectrum, and then TABULATE the data showing the peak number and the bond associated with that peak. Note: Don't try to interpret every peak. Only report the important functional group signals.

3. Justify how the IR data supports the identity of the unknown solid.

4. List and Briefly explain the trend of the C=O bands obtained for the class data of the compounds that were put on the board. How does the trend compare to reference samples? Explain why the different carbonyl groups have different IR absorption frequencies and how this relates to their polarity and functional groups.
