What role does BH3 play in a chemical reaction?
BH3, or borane, acts as a Lewis acid in chemical reactions by accepting a pair of electrons from a Lewis base. This allows BH3 to participate in various reactions, such as hydroboration, where it adds to unsaturated compounds like alkenes. BH3's ability to form bonds with other molecules makes it a versatile reagent in organic chemistry.
How many moles of BH3 are in 5.00 g of BH3?
To find the number of moles of BH3 in 5.00 g of BH3, you first need to determine the molar mass of BH3. The molar mass of BH3 is 11.83 g/mol. Next, divide the given mass by the molar mass to find the number of moles. Therefore, in 5.00 g of BH3, there are 5.00 g / 11.83 g/mol ≈ 0.423 moles of BH3.
Does the Lewis structure of BH3 contain an atom that does not obey the octet rule?
Yes, in the Lewis structure of BH3, the boron atom does not follow the octet rule as it only has 6 electrons around it (2 electrons from each B-H bond). Boron is an exception to the octet rule and can form stable compounds with incomplete octets.
Chemical formula of boron trihydride?
it is BH3
What is the mechanism of the BH3-THF reaction with carboxylic acids?
The BH3-THF reaction with carboxylic acids involves the formation of an intermediate complex between BH3-THF and the carboxylic acid, followed by the reduction of the carboxylic acid to an alcohol.
How many bonds should be drawn in the Lewis-dot structure for BH3?
In the Lewis dot structure for BH3, there should be 3 bonds drawn. Each hydrogen atom forms a single covalent bond with the boron atom. Boron has three valence electrons, so it can form three bonds with the hydrogen atoms.

Why bh3 polymerizes but not ch4?
because ch4 has an octett and bh3 not so it dimerises to b2h6
What is BH3's bond angle?
BH3 has a bond angle of 120 degrees.
How many grams are in 6.3 moles of BH3?
6.3(mol) * 13.83 (g·mol−1)= 87.1 gram BH3
WHY BH3 POLYMERISES BUT CH4 DOESNOT?
BH3 polymerizes due to its ability to form coordinate covalent bonds with other BH3 molecules, creating a network of boron atoms through the sharing of electron pairs. This is facilitated by the electron-deficient nature of boron, which allows it to accept electrons and bond with other BH3 units. In contrast, CH4 (methane) has a stable tetrahedral structure with strong single covalent bonds between carbon and hydrogen, lacking the ability to further bond or react in a way that would lead to polymerization. Thus, the chemical properties and bonding characteristics of BH3 allow for polymerization, while CH4 remains a stable, non-reactive molecule.
