- The molecule contains four oxygens, and from the analysis, contains six double bonds, carbonyls or rings. The large number of degrees of unsaturation strongly suggests an aromatic compound (DU = 4).
- The mass spectrum displays a molecular ion, an m-45 and a peak at m/e = 91, all of which are consistent with a molecule containing benzyl and ethoxy groups.
- The 13C spectrum contains six peaks, indicating that the molecule has some elements of symmetry. The quartet at d 56 and the triplet at d 71 represent a CH3 and a CH2 group which are deshielded by electronegative atoms (most likely oxygen); the peaks at d 161 - 128 are in the aromatic region; the fact that three doublets and one singlet are observed strongly suggests monosubstitution.
- The proton NMR also shows evidence for two ethyl groups, a CH-CH2- group, and a monosubstituted aromatic group; the chemical shift suggests that the carbons of the CH-CH2- adjacent to one or more electronegative groups.
- The IR is consistent with an aromatic compound containing a carbonyl group.
- The simplest structure which is consistent with all of these data would be an aromatic compound linked via a -CH2CH group to a diethyl ester.
