Assign the peaks for the 1H and 13C-NMR spectra of the diolusing the following numbering system. Hint: We can work out via 2Dmethods that in the 13C-NMR the chemical shift of #4 > #3 >#5
\begin{tabular}{|l|l|l|} \hline 1H-NMR peak & mult. & protons \\ \hline 7.15−7.25 & m & ? \\ \hline 7.1 & brs & ? \\ \hline 4.95 & brs & ? \\ \hline 4.75 & s & ? \\ \hline \end{tabular} \begin{tabular}{|l|l|} \hline13 C-NMR peak & carbons \\ \hline 140.0 & ? \\ \hline 128.1 & ? \\ \hline 127.9 & ? \\ \hline 127.0 & ? \\ \hline 73 & ? \\ \hline \end{tabular}
