How could these resonance structures be used to distinguish the spectra? (Think about, in particular: a) How can the chemical shifts of the vinylic protons be used to distinguish which spectrum belongs to which compound? b) How can the chemical shift of the aliphatic (i.e. sp.) methylene group be used to distinguish which spectrum belongs to which compound?)
