(18 pts tota) For Spectra E and F. Spectrum E: This is an expansion of the 3.9 ppm region of the aldol addition product spectrum. OHa Hb N Hd Hc NO2 Fragment Fragment spectrum F: This is an the ppm region of the aldol condensation product pectrum. expansion of 7-9 Ha Hb NO2 Fragment Fragment (8pts) n each spectrum, search for the signals associated with Fragments A and B and label accordingly. Note that the actual chemical shifts may deviate slightly from spectra A and B but the shapes and relative shifts will be similar.Explanation / Answer
SPECTRUM E
FRAGMENT A = 8.7, 7.6, 7.9 8
FRAGMENT B = 7.5 DOUBLET & 8 DOUBLET
SPECTRUM F
FRAGMENT A = 8.8 DOUBLET 8.3 DOUBLET 8.2 BOUBLET, 7.5 MULTIPLET
FRAGMENT B = 7.8 TO 8.0
