In the reaction.
`2X + B_(2) h_(6) to [BH_(2) (X_(2))]^(+) [BH_(4)]^(-)`
X cannot be

A

`NH_(3)`

B

`CH_(3)NH_(2)`

C

`NaH`

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
When `X=H^(-), NH_(3), CH_(3)NH_(2)` then `[BH_(2)(X)_(2)]^(+) [BH_(4)]^(-)`
if `X=CO`, THF then `2[BH_(3) larr X]`
