Question

Observe the main absorption band of the acetone spectrum and assign the peak corresponding to the vibration of the carbonyl group to the spectrum. What is the corresponding wave number?

Answer 1

The main absorption band of acetone typically occurs in the infrared region of the electromagnetic spectrum. The peak corresponding to the vibration of the carbonyl group is typically observed in the vicinity of the 1700 cm^-1 wave number (wavenumber).

The specific wavenumber may vary slightly depending on the experimental conditions and the instrument used for measurement. However, a peak around 1700 cm^-1 is commonly associated with the stretching vibration of the carbonyl (C=O) bond in acetone.
