An alkali metal hydride (NaH) reacts with diborane is 'A' to give a tetrahedral compound 'B' which is extensilve used as reducing agent in organic synthesis. The compoun d 'A' and'B' respectively. Are

A

`CH_(3)COCH_(3)` and `B_(3)N_(3)H_(6)`

B

`(C_(2)H_(5)_(2)O` and `N aBH_(4)`

C

`C_(2)H_(6)` and `C_(2)H_(6)` and `C_(2)H_(5)Na`

D

`C_(6)H_(6)` and `NaBH_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
The compound 'A' is diethylether (solvent) while compound 'B' is sodium borohydride `(NaBH_(4))`.
`2NaH+B_(2)H_(6)underset((A))overset((C_(2)H_(5))_(2)O)rarr2NaBH _(4)`
