Diborane is a Lewis acid forming addition compound `B_(2)H_(6).2NH_(3)` with `NH_(3)`, a Lewis base. This

Options

A. Is ionic and exists as `[BH_(2)(NH_(3))_(2)]^(2+)` and `[BH_(4)]` ions
B. On heating, is converted into borazine, `B_(3)N_(3)H_(6)` (called inorganic benzene)
C. both (a) and (b)
D. Neither (a) nor (b) is correct

Answer

C

Explanation

At low temperature, an addition product.
`B_(2)H_(6).2NH_(3)`, exists as `[BH_(2)(NH_(3))_(2)]^(-)` and `[BH_(4)]^(+)` ions
`3B_(2)H_(6).2NH_(3)overset(200^(@)C)to underset("Borazole")(2B_(3)N_(3)H_(6))+12H_(2)uarr`
