A compound of boron X reacts at 200^(@)C...

A compound of boron `X` reacts at `200^(@)C` temperature with `NH_(3)` to give another compound `Y` which is called as inorganic benzene. The compound `Y` is a colourless liquid and is highly light sensitive. Its melting point is `-57^(@)C`. The compound `X` with excess of `NH_(3)` and at a still higher temperature gives boron nitride `(BN)_(n)`. The compounds `X` and `Y` are respectively :

A

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

B

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

C

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

D

`B_(4)C_(3), C_(6)H_(6)`

Text Solution

Verified by Experts

The correct Answer is:
C

The reactions involved are
`underset((X))(3B_(2)H_(6))+6NH_(3) rarr underset((Y))(2B_(3)N_(3))H_(6)+12H_(2)`
Y is Borazole which is isosteric with benzene.
