2. Pentaborane, B5H9, is an important precursor for higher boranes. It is prepared by the thermal degradation of even lower boranes, as shown below: Na[B3H8] + HCI Na[B3H7CI] + H₂ Step 1 A Na[B3H7CI] B5H9 + NaCl + H₂ Step 2

c. B5H9 can be reduced by elemental sodium to give the salt Na2B5H9 - what happens to the cage in this process and why? [3 marks] d. Reaction of Na2B5H9 with silicochloroform (HSiC13) at high temperature results in the formation of a new cluster, NaSiB5H6. Using Wade's rules, predict the structure of the cluster. How many environments will it possess in the ¹H and ¹¹B{¹H} NMR spectra? [4 marks]
