Please verify the answers that are already there for a-c. The remainder, I cant figure out. Can you please answer and explain this problem step by step please.

1. Compound X has an empirical formula of C10H13NO2. Given are the following spectra. a. What would be the mass of the molecular ion peak (M+)in the Mass Spec? 10(12)+13(1.008)+14.01+16(2) 120+13.104+14.01+32=179.114 b. How many degrees of unsaturation does the compound have? c. If it has any unsaturation, list all the possible combinations. d. Assign three pertinent peaks in the IR spectrum. e. Suggest a structure for compound X based on the spectra given. Show all your work and clearly indicate what your final answer is.
