WebDiborane vapors are heavier than air and may collect in low-lying areas. Diborane is highly irritant when it contacts moist tissues such as the eyes, skin, and upper respiratory tract and can cause thermal burns. Burns are caused by the exothermic reaction of hydrolysis. Ingestion of diborane is unlikely since it is a gas at ambient temperatures. WebDiborane, `B_(2)H_(6)`, canbe prepared by the reaction: `3NaBH_(4) + 4BF_(3) rightarrow 3NaBF_(4) + 2B_(2)H_(6)` In this reaction has a 70 percent yield,...
