5. The following three 13C NMR spectra are of the compounds diphenylacetylene, benzil and hexaphenylbenzene (pay attention to ppm-scale, different for each spectrum). Determine which spectrum corresponds to which compound. Assign the signals of each spectra to the corresponding carbon atom in each compound.
