Homework Answers
1) The NMR spectrum shows: a doublet with integration of 2H, a triplet with integration of 2H and a triplet with integration of 1 H. This is a characteristic spectrum of monosubstituted benzene
2) IR spectrum shows
weak peak at 3053 (could be C-H from arene or alkene)
Medium peak at 1694 (could be C=C from alkene or arene)
weak peak at 1418 (could be C-H in-plane bend)
Strong peak at 1285 (could be C-H in-plane bend from alkene or arene)
strong peak at 740 (characetrstic of arene)
Based on NMR and IR spectra the compound is a monosubstituted Benzene.
