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

Options

A. `CH_(3)COCH_(3)` and `B_(3)N_(3)H_(6)`
B. `(C_(2)H_(5))_(2)O` and `NaBH_(4)`
C. `C_(2)H_(6)` and `C_(2)H_(5)Na`
D. `C_(6)H_(6)` and `NaBH_(4)`

Answer

B

Explanation

`underset(" Sod. hydride ")(2NaOH) + B_(2)H_(6) overset((C_(2)H_(5))_(2)O (A))underset(" Diethyl ether ")rarr underset((" Tetrahedral complex "))underset(" Sod. Borohydride (B) ")(2Na^(+)[BH_(4)]^(-))`
