Explanation:
IR Spectrum:
The IR spectrum shows a band at 1170 cm-1, which corresponds to the C-O stretching frequency of an ester group.
Carbon-13 NMR Spectrum:
The C-13 NMR spectrum shows four peaks at 178 ppm, 68 ppm, 28 ppm, and 22 ppm. These peaks give information about the types of carbon atoms present in the compound and their chemical environment.
- The peak at 178 ppm corresponds to a carbonyl carbon (C=O) in an ester group.
- The peak at 68 ppm corresponds to a carbon atom in a double bond (C=C).
- The peak at 28 ppm corresponds to a carbon atom in a methyl group (CH3).
- The peak at 22 ppm corresponds to a carbonyl carbon (C=O) in a ketone group.
Structure:
From the IR and NMR spectra, it can be concluded that the compound has an ester group and a ketone group. Also, there is a double bond and a methyl group in the compound. Therefore, the correct structure of the compound is:
CH3COCH=CHCH3O2CCH3
This is 3-methylbut-2-en-1-yl acetate.
