What is the NMR structure given the information provided?

The NMR spectrum, IR spectrum, and molecular formula are the only things that were provided for the question. I'm trying to figure out what the structure would be give the information.

Answer 1

Molecular formual CH15NO DBE =C+1 - H/2 +N/2 = 7+1 -15/2 + 1/2 = 8.5 - 7.5 = 1 IR shows that strong peak at 1640 cm-1 which is due to amide C=0 streching. It also shows a broad doublet at 3200-3400 cm-1 which is due to N-H streching 1 H NMR shows a 9H, singlet at 1.00 ppm which is due to C(CH3)2 group It also shows a 3H triplet at 1.2 ppm and a 2H, quatret at 3.6 ppm which is due to CH CH3 group. There is a 1H, multiplet a 3.9 ppm which is due to NH group. All these information suggests below structure H3C CH3 Нас C7H15NO 1 H NMR Estimation 3.6. 2H, a H3C ZI CH3 1.20, 1.00, 9H, $* -H3C --CH? 3.9, 3H, t 1H, m
