Provide a brief justification for the identification of 1-propanol, hexane, benzyl alcohol, 1-hexanol and ethyl benzoate based on 2-3 key bands in each spectrum, which suggest the presence (or absence) of specific functional groups. You do not need to identify all the bands in the spectra -that would be almost impossible. If the bands are too similar (or in addition, to strengthen your discussion), you could look the IR spectra of the compounds in a database and see whether the IR of the unknowns can be identified this way.

NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.
