1. Reaction of BF\(_3\) with LiAlH\(_4\) in diethyl ether: BF\(_3\) + LiAlH\(_4\) \(\rightarrow\) B\(_2\)H\(_6\) + LiF + AlF\(_3\) Products: Diborane (B\(_2\)H\(_6\)), Lithium fluoride (LiF), Aluminum fluoride (AlF\(_3\)) No hydrogen (H\(_2\)) is formed.
2. Hydrolysis of diborane: B\(_2\)H\(_6\) + 6H\(_2\)O \(\rightarrow\) 2B(OH)\(_3\) + 6H\(_2\) Products: Boric acid (B(OH)\(_3\)), Hydrogen (H\(_2\)) 3. Oxidation of sodium borohydride with iodine: 2NaBH\(_4\) + I\(_2\) \(\rightarrow\) 2NaI + B\(_2\)H\(_6\) + H\(_2\) Products: Sodium iodide (NaI), Diborane (B\(_2\)H\(_6\)), Hydrogen (H\(_2\))
4. Combustion of diborane: B\(_2\)H\(_6\) + 3O\(_2\) \(\rightarrow\) B\(_2\)O\(_3\) + 3H\(_2\)O Products: Boron trioxide (B\(_2\)O\(_3\)), Water (H\(_2\)O) No hydrogen (H\(_2\)) is formed. Therefore, hydrogen is formed in reactions (ii) and (iii).
