Question

give the preparation of diborane​

Answer 1

Answer:

1:-Diborane can be obtained by reducing BF₃ with LiAlH₄ in diethyl ether.

4BF₃ + 3LiAlH₄——>2B₂H6 + 3LiF + 3AlF₃

2:-In laboratory,diborane is prepared by the oxidation of sodium borohydride with iodine.

2NaBH₄ + I₂——->B₂H6 + 2NaI + H₂

3:-In industry, diborane is prepared by the reaction of BF₃ with sodium hydride.

2BF₃ + 6NaH——>B₂H6 + 6NaF
