Hydrides and H2O

Boron forms a numbr of hydrides having the general formuale B_(n)H_(n+4)1 and B_(n)H_(n+6) These hydrides are called boranes. The simpest hydride of boron is diborane, B_(2)H_(6) . Boranes contain special types of bonds known as multicientre bonds. Bornaes have high of combustion. From B_(2)H_(6) . which of the following can b e prepared except:
