What are boranes ? Give chemical equation for the preparation of diborane. |
|
Answer» SOLUTION :Boranes are the binary compounds of boron and hydrogen like an Alkanes. These are covalent hydrides of formula `B_2H_6` called diborane. PREPARATION of diborane : It is prepared by treating boron trifluoride with `LiAlH_4` in diethyl ETHER. `4BF_3 + 3LiAlH_4 to 2B_2H_6 + 3LiF + 3AlF_3` `B_2H_6` is produced on an industrial scale by the REACTION of `BF_3` with NaH (Sodium HYDRIDE) `2BF_3 + 6NaH overset"450 K"to B_2H_6 + 6NaF` |
