WebApr 12, 2024 · Diborane is an inorganic compound having the chemical formula B 2 H 6. This compound contains boron and hydrogen atoms in a cyclic structure. It occurs as a colourless and pyrophoric gas. It has a repulsive sweet odour as well. The molar mass of diborane is 27.67 g/mol. Figure 02: Structure of Diborane WebAug 15, 2024 · Diborane can be synthesized by an exchange reaction (metathesis) of a boron halide with LiAlH 4 or LiBH 4 in ether, for example: (1) 3 LiAlH 4 + 4 BF 3 2 B 2 H 6 + 3 LiAlF 4 The reaction has to be done under vacuum or with exclusion of air, because diborane burns in contact with air.

WebStructure of diborane: In diborane two BH2 units are linked by two bridged hydrogens. Therefore, it has eight B-H bonds. However, diborane has only 12 valance electrons and are not sufficient to form normal covalent bonds. The four terminal B-H bonds are normal covalent bonds (two centre - two electron bond or 2c-2e bond). WebDiborane is a molecule with the formula B 2 H 6.
