The stretching frequency (in cm⁻¹) of the given carbonyl compound is 1685 cm⁻¹
The carbonyl group, C=O, has a large dipole moment and it creates an intense stretching vibration whose peak generally appears between 1600 to 1800 cm⁻¹.
The spectrum shows a stretching absorption consistent with a ketone functional group, i. e. carbonyl group C=O stretching at ~1685 cm⁻¹.
Definition: Stretching frequencies are higher than corresponding bending frequencies. It is easier to bend a bond than to stretch or compress it.
The distinctive carbonyl band is particularly useful for diagnostic purposes because it has a characteristic high intensity and few other functional groups absorb in this region.
Different carbonyl compounds absorb in narrow ranges within the general carbonyl region.
