Homework Answers
- Peak in IR at 1739 cm-1 indicates the presence of ester functional group in the compound.
- The presence of ester group is confirmed by peak at 175 ppm in 13C-NMR
- 6H singlet at ~3.6 ppm indicates that this group is attached to oxygen
- 4H singlet at ~2.7 ppm indicates that this group is attached to Carbonyl
- Therefore formula of compound is C6H10O4 M= 146 m/z
CH3C(O)CH2CH2C(O)CH3
CH3C(O)CH2CH2C(O)CH3
