Please identify Molecule A, formed from the reaction shown, from the 13C NMR spectra shown. All peaks below are single peaks (no overlapping peaks). Inset is an expansion of the downfield section of the spectra.

Can you elaborate step by step if this H-NMR is correct or not?

Draw the product structure and label each unique hydrogen atom with a letter. Label the NMR spectral peaks with letters corresponding to each hydrogen atom.

4. Ethyl acetate gives a base peak at m/z 43, and a peak at m/z 61. Draw the structures of the fragments that give rise to these peaks. H₂C CH3
