(a) Interpretation: The 1 H and 19 F spectra of FC 2 H should be predicted. Concept introduction: Spin-spin coupling is a phenomenon which is caused by the spin coupling between two chemically different nuclei which are NMR active. This effect is indicated through peak splitting in NMR spectra. Coupling constant is a measure of interactions between NMR active nuclei.
