Homework Answers
IR spectrum
The IR spectrum contains sp3 CH stretching around ~ 2950 cm-1
C=O stretching is present ~ 1700 cm-1
Mass spectrum
The molar mass of the compound is 130 m/z
1H NMR
The quartet and triplet from 4.0 ppm and 1.3 ppm belongs to ethyl group which attached to oxygen directly. The The peak 2.2 ppm belongs to CH3 group which is attached to carbonyl carbon. The another peak at 3.3 ppm is belongs CH2 that lies between two carbonyl group. Using all the information we can deduce the structure.
