(a)   Into how many peaks will the proton signal in the 1H NMR spectrum of methyl fluoride be split?

(b)   Into how many peaks will the fluorine signal in the 19F NMR spectrum of methyl fluoride be split?

(c)   The chemical shift of the protons in methyl fluoride is 8 4.3. Given that the geminal 1H— l9F coupling constant is 45 Hz, specify the δ values at which peaks are observed in the proton spectrum of this compound at 200 MHz.
