2015年7月22日 · Note that this mechanism does in fact include hydride transfers (it has to). Though you were right in thinking that $\ce{BH3}$ wouldn't immediately donate a hydride, …

2022年1月30日 · If we suppose that the carbonyl compound is first reduced to an alcohol, removal of the hydroxyl group would require formation of a radical or ion, which in an aromatic …

2014年11月29日 · $\ce{BH3}$ Borane dimerizes because the boron atom is electron deficient - it has an empty p orbital. This species is so electron deficient that it will form bonding …

2012年5月4日 · $\ce{B}$ has an $2s^22p^1$ valence shell, so three covalent bonds gives it an incomplete octet. $\ce{BH3}$ has an empty $2p$ orbital. This orbital overlaps the existing …

2020年2月20日 · As per this source, the idea and definition of oxidation state is based on the following principle:. The oxidation number of an atom in a molecule is based on a formalism …

2017年6月29日 · First, I understand that, on $\ce{BH3}$, they eletronegativity difference between $\ce{B}$ and $\ce{H}$ is very small. Which mean that the $\ce{B-H}$ bond is less polarized. …

2015年4月22日 · Still, compounds that don't have an octet, like $\ce{BH3}$, tend to dimerize or disproportionate in order to achieve an octet. In recent SE Chem posts discussing the bonding …

2014年5月15日 · $\ce{BH3}$ is a flat triangle molecule, so it has mirror symmetry. Since the dipoles cancel out, the molecule does not have a dipole moment. Since the dipoles cancel out, …

So I was a bit confused. Hydrogen and Boron seem to be the only outliers to the octet rule. Hydrogen makes sense because it has only one shell and 2 electrons complete its shell.

2018年6月11日 · Naming an ionic compound from its formula. Name the cation and then the anion. ("sodium sulfate", but not "sulfate sodium"). (How to identify the cations and anions in …
