The only thing I can think of is the size match between Cl and the B or Al; there's more likely to be an interaction between the vacant AO on Al than B and the Cl lone pairs because the AOs are better matched in energy and size, making the bonding interaction more favourable.
I might be talking rubbish but that's one theory anyway!
A.P.
What else can I help you with?
Why bh3 polymerizes but not ch4?
because ch4 has an octett and bh3 not so it dimerises to b2h6
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.
Why bh3 has less boiling point compared to nh3?
BH3 is non polar.Inter moleculer forces are much weaker Wander Voals forces.NH3 have hydrogen bonds among molecules.They are very strong comparing to Vander Woals forces.So NH3 have high boiling point.
WHY BOND ANGLE DECREASES WHEN WE MOVE FROM NH3 TO BH3?
The bond angle decreases from NH3 to BH3 primarily due to the difference in the presence of lone pairs and the types of bonding orbitals involved. NH3 has a lone pair on nitrogen, which exerts repulsion and pushes the hydrogen atoms closer together, resulting in a bond angle of about 107 degrees. In contrast, BH3 has no lone pairs on boron and adopts a trigonal planar geometry with bond angles of approximately 120 degrees. However, the effective repulsion from the empty p-orbitals in BH3 leads to a slight decrease in bond angle compared to the ideal trigonal planar geometry.
What is the chemical formula of boron and hydrogen?
BH3. but the compound generally exists as its dimer B2H6.
What is the name of the covalent compound BH?
BH is not stable, there is no compound by that formula. BH3 (boron hydride) generally exists as the dimer, B2H6, diborane.
How do you write a formula for the compound of boron chloride?
The formula for boron chloride is BCl3. This compound consists of one boron atom bonded to three chlorine atoms.
What is the melting point of BH3?
The predicted boiling point for borane is 440,34 oc.
Bh3 can't exist but bx3 can exist why?
In chess notation, "Bh3" typically refers to moving the bishop to the h3 square, which is not a legal move. On the other hand, "bx3" refers to capturing a piece on the x3 square with a pawn or bishop, which is a valid move. The "b" in "bx3" signifies the piece making the capture, while "x3" indicates the square of the captured piece.
Which is the increasing acidity order of those Lewis acid BF3 BBr3 BI3 BCl3?
The increasing acidity order of these Lewis acids is: BCl3 < BBr3 < BI3 < BF3. This trend is due to the decreasing ability of the halogen to stabilize the negative charge on the Lewis acid, leading to increased acidity as you move from BCl3 to BF3.
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.
Chemical formula of boron trihydride?
it is BH3
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
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.
