Verified by Experts

`BCl_(3) +H_(2) overset("Silent electric discharge")rarr (A) + HCl`
`(A) + NH_(3) overset(200^@C)rarr (B)`
`2BCl_(3) + 6H_(2) overset("Silent electric discharge")rarr underset((A)) (B_(2)H_(6) ) + 6HCl`
`3B_(2) H_(6) + 6NH_(3) overset(200^@C)rarr underset((B))(2B_(2) N_(3) H_(6)) + 12 H_(2)`
`(A)` is diborane and `(B)` is borazine.
