The substitution pattern in an arene molecule refers to the arrangement of substituent groups around the aromatic ring. The 13C NMR spectrum of an arene can provide information on the number and types of carbon atoms present in the molecule, as well as their chemical environment. Different substitution patterns can lead to unique 13C NMR spectra, allowing for the identification of the substitution pattern in aromatic compounds.
18C warmer than -13C is 5C.
The compound has three unique 13C NMR signals.
