# Heating of diborane with excess of ammonia to a high temperature yields

$\begin {array} {1 1} (A)\;\text{borane} & \quad (B)\;\text{diammoniate of borane} \\ (C)\;\text{borazine} & \quad (D)\;\text{borone nitride} \end {array}$

$B_2H_6 \large\frac{excess\: NH_5}{high\: temp}$$(BN)_x$
Hence option (C) is the correct answer.
