Question Assign the peaks in the 1H NMR spectrum of your product. Hand-draw your structure on the NMR spectrum and label each set of inequivalent protons. Use these labels in assigning the peaks. In some cases, the aromatic peaks may overlap, so it is acceptable to assign multiple groups of protons to a series of overlapping peaks if necessary; nevertheless, try to be as specific as possible in your assignment. Discuss in detail how the NMR spectrum is consistent only with your proposed structure. Describe the features, unique to your structure, that match your spectrum; also, what features are absent that allow you to discount other possible structures? starting products: acetone and cinnamaldehyde product: dicinnamalacetone Full spectrum ONMtotonomon OOON WOONMoin NTNO mmmmmm օօօօտտ GOLOLOLOLOL 1.605 0.001 4 NL 62 0 8 7 5 Jub b - MEApp: ចងចាំ ៗ Nob أبدأ بة بة به 6.923 p26 6,556 Aromatic region 41 4 6. 2 T 7. 7.5 4 7.3 7.2 7.1 7.0 T 6.8 G 6. 6.6 6.5

starting products: acetone and cinnamaldehyde
product: dicinnamalacetone
Solution: The 1H NMR spectrum of dicinnamalacetone along with the labelled signals is attached here as an image.1H NMR s pectrum of dicinnalactone The number of peaks and the number of hydrogens present in the given spectrum suggests that it is a symmetrical compound (dicinnamalacetone). Also, all the peaks fall within the alkene or the aromatic region that also supports that the given spectrum belongs ... See the full answer
