WebUnlike hydride ions, which are electron-rich nucleophiles, diborane is the dimer of an electron-deficient electrophilic species (BH 3). It is formed by reaction of a borohydride ion with strong acids and is used in 2.2′-dimethoxydiethyl ether (diglyme) as the solvent. Diborane reacts faster with carboxylic acids, reducing them to primary ... http://www.chem.ucla.edu/~cantrill/30A_F05/Diborane.pdf
Why BCL3 is monomer but BH3 exists as Dimer? - Answers
BH3 is a trigonal planar molecule with D3h symmetry. The experimentally determined B–H bond length is 119 pm. In the absence of other chemical species, it reacts with itself to form diborane. Thus, it is an intermediate in the preparation of diborane according to the reaction: BX3 +BH4 → HBX3 + (BH3) (X=F, Cl, … See more Trihydridoboron, also known as borane or borine, is an unstable and highly reactive molecule with the chemical formula BH 3. The preparation of borane carbonyl, BH3(CO), played an important role in exploring the … See more Molecular BH3 is believed to be a reaction intermediate in the pyrolysis of diborane to produce higher boranes: B2H6 ⇌ 2BH3 BH3 +B2H6 → B3H7 +H2 (rate determining … See more • Butterfly cluster compound See more WebWhich of these two: NF3 and NH;has greater tendency to do so? and give reason for your choice.
