An alkali metal hybride `(NaH)` reacts with diborane in Y to give a tetrahedral compound Z, which is extensively used as reducing agent in organic synthesis. The Y and Z in the above reaction are

A

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

B

`C_(2)H_(5)-O-C_(2)H_(5), NaBH_(4)`

C

`NH_(3), B_(3)N_(3)H_(6)`

D

`C_(3)H_(8), C_(3)H_(7)Na`

Text Solution

Verified by Experts

The correct Answer is:
B
The required reaction is
`2NaH+B_(2)H_(6)underset((Y))(("In "C_(2)H_(5)-O-C_(2)H_(5)))rarr underset((Z))(2Na^(+)[BH_(4)]^(-)) ("tetrahedral " BH_(4)^(-) " ion")`
