1) By reduction of boron trifluoride with lithium hydride.

8 BF3 + 6LiH - > B2H6 + 6LiBF4

B2 H6 - Diborane.

2) By electric discharge.

2BCl3 + 6H2 - > B2H6 + 6HCl.

Answer 2

ANSWER✔✔↙️↙️

Diborane is prepared by treating boron trifluoride with LiAlH4 in diethyl ether.

In labs it is prepared by the Oxidation of sodium boro hydride with iodine.It is prepared by acid hydrolysis of magnesium boride
