Nov 11, 2017 · Ex) BH3 Trigonal bipyramidal has a VSEPR formula of AX5E0, meaning that the molecule has 5 bonded pairs and 0 lone pairs on the central atom, making the bond angles 90 degrees and 120 degrees.

Nov 22, 2023 · We can assess the bond angles of molecule using how it appears in it's lewis structure. For example, a trigonal planar formation (like Boron Hydride BH3) would have 120 degree bond angles while a liner structure like CO2 would be 180 degrees.

Dec 3, 2021 · When drawing the lewis structures of NH3 and BH3, it's apparent that there is a lone pair of electrons on the central atom N for NH3. This lone pair of electrons can be donated, thus classifying it as a lewis base.

Nov 19, 2018 · Can someone please explain this homework problem? "State the hybridization of the atom in boldface type in each of the following molecules: a) BeCl2 (Be) b) BH3 (B) c) BH4- (B) d) SiF4 (Si) Thank you !!

Feb 9, 2016 · If it were BH3, W would be 1 because, no matter how it's arranged, Boron would be surrounded by three hydrogens. Now consider this as if the molecule were a crystal (this is just a metaphor, a single molecule couldn't be a perfect crystal I think).

Nov 16, 2023 · What is the VSEPR theory and how can you determine the molecular shape of the molecule from it? A question on one of the midterm practice worksheets asked for the VSEPR formula, shape, and hybridization of the perchlorate anion: ClO4^-.

Nov 25, 2020 · What would be the shape of H2O? Is it tetrahedral or Trigonal Pyramidal??

Jan 17, 2022 · For example, there's no change in hydrogen bonding in the reaction H3C + NH2 + BH3 --> H3C + NH2+ + BH3-. There's no donation nor acceptance of the proton H+, but NH2 is considered a Lewis base because it donates an electron pair and BH3 is a Lewis acid because it accepts an electron pair. Just keep that in mind!

Oct 23, 2015 · 1. According to the book, molecules that are AX3E2 are T-shaped. The illustration of the molecule shows that the lone pairs replace 2 of what would be the equatorial atoms, which would make them 120 degrees from each other. Since there is electron repulsion, why don't the lone pairs replace the top and bottom atoms so they can be 180 degrees from each other (like AX4E2)? 2. Does the atoms in a ...

Nov 25, 2023 · the VSEPR theory helps determine the molecular geometry by considering the arrangement of electron pairs around a central atom. Hybridization is a concept that explains the mixing of atomic orbitals to form new hybrid orbitals, which influence the molecular shape. The VSEPR theory and hybridization work together to predict …
