Compound (X) on reduction with LiAlH(4) ...

Compound `(X)` on reduction with `LiAlH_(4)` gives a hydride `(Y)` containing `21.72 %` hydrogen along with other products. The compound `(Y)` reacts with air explosively resulting in formation of boron trioxide. Identify `(X)` and `(Y)`.
Give balanced reactions involved in the formation of `(Y)` and its reaction with air. Give the structure of `(Y)`.

A

`BCI_(3), B_(2)H_(6)`

B

`B_(2)H_(6), BCI_(3)`

C

`BF_(3),AI_(2)O_(6)`

D

`B_(2) H_(6), BF_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`underset((X))(4BCI_(3)) + 3LiAIH_(4) to underset((Y))(2B_(2)H_(6)) + 3AICI_(3) + 3LiCI`
Percentage of hydrogen in`B_(2)H_(6) = (6)/(27.62) xx 100 = 21.72`
`B_(2)H_(6)+ overset("Explosion")(to) B_(2)O_(3) + 3H_(2) O`
