Answer:
The label of spectrum is attached.
Explanation:
adipic acid is equal to:
COOH - CH2 - CH2 - CH2 - CH2 - COOH
(1) (2) (3) (3) (2) (1)
The structure of adipic acid indicates that it has 3 equivalent carbons, therefore it should have 3 peaks in the spectrum:
The first peak at approximately 172 ppm is from carbon (1) COOH. The second peak is at approximately 23 ppm and is by carbon number (3) CH2. and the third peak is at approximately 37 ppm and is due to group number (2) CH2.
