Question
Identify each compound in the following questions and make assignments in the 1H NMR

a) First spectra: Compound 1, 1H NMR given, and has a strong absorbance in the IR at 1715 cm-1

b) Second spectra: Compound 2, a carboxylic acid of formula C8H6O3Cl2 with 1H NMR given

c) Third spectra: Compound 3 with molecular formula of C6H9ClO2, with 1H NMR given (the four signal from highest to lowest chemical shift are quartet, quartet, double, and triplet)

d) Compound 4, with a molecular formula of C7H7NO3, and the aromatic region of the 1H NMR is given. An additonal singlet in the 1H NMR is observed at 4.1 ppm that integrates to 3 hydrogens. Assign each aromatic proton and make sense of the coupling patterns (coupling constants for aromatic protons are usually about 8 Hz for ortho protons, 1-2 Hz for meta protons, and 0 Hz for para protons)
