Question

7. Shown below are the spectra (labeled A and B) for the reactant and product in a bromination reaction. One spectrum shows C$_3$H$_6$Br$_2$O and the other one shows C$_3$H$_6$O. Identify which spectra is which, draw the two structures for the reactant and product and then explain which peaks in the NMR spectra correspond to the hydrogens in the structure. Spectrum A (c) and (d) 3H, singlet (a) C$_3$H$_6$Br$_2$O 1H, doublet doublet of doublets, 1H (b) 7 7 1H, doublet 6 5 4 3 2 0 PPM 1H, triplet (c) 2H, multiplet (b) 6 5 3H, singlet (a) Spectrum B C$_3$H$_6$O 4 3 2 1 0 PPM POST LAB
