Question

A compound o f boron X reacts at 200°C temperature with NH3 to give another compound Y which is called as inorganic benzene. The compound Y is a colourless liquid and is. highly light sensitive. Its melting point is -57°C . The compound X with excess of NH3 and at a still higher temperature gives boron nitride (BN)n The compounds X and Y are respectively : (A) BH3 and B2H6 (B) NaBH4 and C6H6 (C) B2H6 and B3N3H6 (D) B4C3 and C6H6

The reactions involved are underset(X)3B2H6+6NH3 → underset(Y)2B3N3H6+12H2; B2H6+NH3 (excess) xrightarrow textat higher temperature (BN)n+H2 Y is borazole which is isosteric with benzene

$B H_{3}$ and $B_{2} H_{6}$

$N a B H_{4}$ and $C_{6} H_{6}$

$B_{2} H_{6}$ and $B_{3} N_{3} H_{6}$

$B_{4} C_{3}$ and $C_{6} H_{6}$

The reactions involved are
$(X) 3 B_{2} H_{6} + 6 N H_{3} \to (Y) 2 B_{3} N_{3} H_{6} + 12 H_{2}$ ;
$B_{2} H_{6} + N H_{3}$ (excess) $at higher temperature (BN)_{n} + H_{2}$
$Y$ is borazole which is isosteric with benzene
