The structure of compound L is to be proposed and the assignment for the peaks in IR spectrum is to be done. Concept introduction: IR spectroscopy is used to determine the presence of functional groups in the compounds. NMR spectroscopy is used to determine the presence of equivalent protons in the structure of the compound. In the IR spectra, benzene shows absorption at 3030 cm -1 for the C − H stretching. Monosubstituted benzene gives peaks between 690 and 770 cm -1 . Para di-substituted benzene gives a strong peak between 800 and 860 cm -1 . Aromatic rings show absorption at 3030 cm -1 due to C − H stretching and between 1600-1400 cm -1 due to C=C stretching vibrations. Alkyl groups show absorption between 2950 and 2850 cm -1 due to C − H stretching.
