Reaction of diborane with oxygen
WebDiborane is a highly reactive gas and produces a green flame when burned in air. The chemical reaction and standard reaction enthalpy for this process is given below. B.H. (g) + 3 0, (9) --B,0, (s) + 3 H,0 (9), AH = - 1958 kJ If 120 mL of oxygen gas at 0.5 atm and 20 °C reacts with 38 mg of diborane, what is the enthalpy change? Plan: Calculations: WebThe reaction is driven by the high affinity of Boron for Oxygen. Diborane, borane and borane complexes all proceed by essentially the same mechanism. Generally, NaBH 4 will not reduce amides, but will in the presence of acids. General comments.
