Given: Melting point of pure solid = 101-106 oC IR: 2837, 1701, 1602, 1391, 1139 cm-1From the given IR data, we can see -C-H stretch at 2837 cm-1 (alkyl group is present) -C=O stretch at 1701 cm-1 (carbonyl group is present) From 1H- NMR data, a signal at ~10 ppm indicates an aldehydic proton a signal at ~2.5 ppm is a singlet of approximately 3 protons indicating a -CH3 group with no adjacent proton. From 13C-NMR data, Signal at ~190 ppm confirms aldehydic carbon Signals from ~130-150 ppm indicate aromatic carbons. Signal at ~20 ppm indicates R-CH3 group From the above data, we can now confirm that R = H and R' = CH3 group. Therefore, our unknown compound, i.e. the product is: All the spectroscopic data matches with the above compound. The melting point is also very close to the observed value.
