When an unknown amine reacts with an unknown acid chloride, an amide with a molecular mass of 163 g/mol (M* = 163 m/z)is formed. In the infrared spectrum, important absorptions appear at 1661, 750 and 690 cm. The 13C NMR and DEPT spectraare provided. Draw the structure of the product as the resonance contributor lacking any formal charges.13C NMRDEPT 902001601208040020016012080400DEPT 135T20016012080400Draw the unknown amide.SelectDowTemplatesMoreFrage

There are four isomers shown below (compounds A-D). TWO of these isomeric nitrogen- containing compounds were extracted and isolated from tobacco leaves. Their structures were determined using 1H NMR. These two 1H NMR spectra are shown below. Make peak assignments of the NON-AROMATIC signals to determine which TWO isomers are represented. Use the specific labels (a-h) provided with spectra.
