Concept explainers
Interpretation:
Each of the given IR spectrum is to be matched with either compound K, L, or M.
Concept introduction:
IR spectroscopy enables to identify different functional groups in the given molecule.
One of the greatest advantages of IR spectroscopy is that the frequency of a particular type of vibration is typically found within a characteristic range of frequencies, regardless of the functional group with which the vibration is associated. The fact that absorptions by certain vibrations appear with characteristic frequency ranges enables us to use IR spectroscopy to obtain structural information about a molecule.
IR absorptions corresponding to bending modes of vibration appear below
