Answer: The infrared spectrum tells us what functional groups are present in a molecule. Explanation: The bonds in molecules are vibrating, and the vibrational energy is quantized. The bonds can stretch and bend only at certain allowed frequencies.

Webb) As previously, the frequency at 1745 cm − 1 ^{-1} − 1 suggests carbonyl. But the lack of frequencies at 1000 and 1250 cm − 1 ^{-1} − 1 tells us that there is no C-O bond in the molecule.. This tells us that it is a compound that does not contain a single C-O bond but only a double one (since this is confirmed by the carbonyl stretching frequency).
