(A) 2 B +2 NH 3 arrow 2 BN +3 H 2 Boron produced BN with ammonia but Boron is element not compound. So that this option not involve in answer. (B) 3 B 2 H 6+6 NH 3 arrow 3[ BH 2( NH 3)2]+[ BH 4-] xrightarrow T =200° C 2 B 3 N 3 H 6+12 H 2 B 3 N 3 H 6 xrightarrow T >200° C ( BN ) x (C) B 2 O 3(ℓ)+2 NH 3 xrightarrow1200° C 2 BN ( s )+3 H 2 O ( g ) (D) HBF 4+ NH 3 arrow NH 4[ BF 4]
