A compound of boron X reacts at 200^(@)C temperature with NH_(3) 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 NH_(3) and at a still higher temperature gives boron nitride (BN)_(n) . The compounds X and Y are respectively:

A compound X, of boron reacts with NH_(3) on heating to give another compound Y which is called inorganic benzene. The compound X can be prepared by treating and Y are represented by the formula.
