WebExplain why phosphine has a significantly lower boiling point than ammonia. [6] a. Phosphine is usually prepared by heating white phosphorus, one of the allotropes of phosphorus, with concentrated aqueous sodium hydroxide. The equation for the reaction is: P4 (s) + 3OH−(aq) + 3H2O (l) → PH3(g) + 3H2PO2−(aq)
