Webshift parameters (Curphy-Morrison parameters) or chemical shift tables found at the end of the exam to assist your 1H-NMR analysis and signal assignments. Assign the hybridization of the 13C-atoms responsible for each 13C-NMR signal. Identify specific functional group signals; you do not need to assign individual carbon atoms to each signal. WebIn the space below: i) Draw product X and the other possible regioisomer ii) Predict the 1 H-NMR coupling pattern for each of the 1 H-nuclei attached to the aromatic ring of each regioisomer (X and Y) and estimate the chemical shift of each signal using empirical (Curphy-Morrison) parameters. Ignore any para coupling. (12 pts) X Y.
