(iii) State how the use of 11B and 31 P NMR spectroscopy can be used to confirm the formation of F3BPD3. This answer requires that you construct labelled line diagrams to predict the NMR spectra in BF3,PD3 and F3BPD3. (You may assume that the 11B nucleus is 100% abundant as a first approximation). [7 marks] (iv) The molecule PD3 was substituted with one hydrogen to produce PD2H. State how 'H NMR spectroscopy can be used to confirm the formation of F3BPD2H. This answer requires that you construct labelled line diagrams to predict the 'H NMR spectra in the PD2H and F3BPD2H. (You may assume that the "B nucleus is 100% abundant as a first approximation).
