How many unique carbon signals are expected for compound (1)? Are the appropriate number of peaks present? (you may need to expand the spectrum) Which hydrogen(s) would be assigned to 18.5 ppm? The carbon signal of an ester C=0 is estimated to be 1600-1800 ppm. Explain why compound (1)'s carbonyl is on the lower end of this range around 161 ppm. 3
