Diborane reacts with ammonia to from X, which on heating gives `H _(2)` and borazine, X is

Options

A. `[BH_(2)(NH_(3))_(2) ]&^(+)[BH_(4)]^(-)`
B. `B_(3) N _(3)H _(6)`
C. `BH_(3). NH_(3)`
D. `[BH(NH_(3))_(3)]^(+) [BH_(4)]^(-)`

Answer

A

Explanation

`B_(2) H _(6) + 2NH _(3) to [BH_(2) (NH_(3))_(2) ]^(+)[BH_(4)]^(-)`
`3 [BH_(2) (NH_(3))_(2) ]^(+) [BH_(4)]^(-) overset(Delta) to 2B_(3) N_(3) H _(6) + 12H_(2)`
