The compounds E-G are to be matched with spectrums 7-9 based on the relative intensities of the alkane C − H absorption bands. Concept introduction: IR spectroscopy enables us to identify different functional groups in the 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. The absorption band for alkene C − H bond appears in the range of 2800 – 3000 cm − 1 . The relative intensity of the alkane C − H band decreases with increase in the number of alkane C − H bonds in the molecule.
