Q-1……………..By
identifing the sprectra provide the information about the structure
, Please provide the structure of the compound. Justification (i.e.
shifts, multiplicities, peaks etc.) for your structure should be
given.
The unknown is dibenzyl sulfoxide
IR:
3000-3100 cm-1, medium, aromatic sp2 =C-H stretch
2850-3000 cm-1, medium, sp3 C-H stretch
1350-1480 cm-1, medium, sp3 C-H bending
1400-1600 cm-1, medium-weak, multiple bands, sp2 C=C stretch
1030 cm-1, strong, S=O stretch
HNMR:
7.51 - 7.13 ppm, 10H, aromatic protons
3.88 ppm, 4H, -CH2- groups attached to S=O group
Mass:
M+ ion peak (Molecular ion peak) at m/z 290 and base peak at m/z 91 due to tropylium cation C6H5-CO+
NMR assignment:
