Complete detailed spectroscopic characterisation of N-methylacetamide : 1H and 13C NMR and if available MS and IR.
please include the required spectra graphs & data while talking about them
Homework Answers
In 1H NMR data a broad peak around 6.4 ppm is observed for N-H. Broadness of the peak is due to exchange with solvent.
A doublet around 2.7-2.9 ppm is for Hc. Doublet is due to coupling with N-H hydrogen. A singlet around 1.9-2.1 ppm is for Ha. Solvent is ignored in spectra.
In 13C NMR spectra a peak around 170 ppm is for Cb. And peaks around 20-28 ppm is for Ca and Cc.
Mass spectra with fragment details is given below

From the spectral data (1H, 13C NMR, IR, MS) you were given,
identify the structure of your product. Explain why you chose your
particular product based on the spectroscopic data.
(b)
Fully assign the 1H NMR spectrum of your product (i.e. determine
which peaks in the 1H NMR correspond to which hydrogens in the
product)
