inorganic chemistry - Why is the Si-F bond one of the strongest single ...
Dec 22, 2019 · I honestly have no clue where to begin explaining why the Si-F bond is one of the strongest single covalent bonds of them all. I would actually predict the bond to be relatively weak on …
Reaction of Silicon Dioxide with Hydrofluoric Acid
Jul 20, 2020 · If you are using comparative bond strengths to determine if a reaction is favorable, you need to consider the bonds in the products as well as those in the reactants. Although H-F has a …
inorganic chemistry - When to consider back bonding and when to not ...
May 31, 2021 · p p π- d d π bonding is very weak and normally not considered to be very effective in bonding. Rather, the bonding can be explained via ionic bonding instead due to the large …
Why is covalent bonding stronger than electrostatic attraction?
Dec 16, 2014 · The article by Gillespie argues you should avoid the phrase "ionic character" because "ionic" and "covalent" aren't mutually exclusive. It's pretty clear from dipole moment in diatomic LiF …
If a molecule has both polar and ionic bonds in it, is it polar or ...
Dec 5, 2016 · To be more specific, lets take a look at the Lewis Structure of two such examples: The first one is SiCl 3 3 F. The red arrow represents an ionic bond while the blue is a polar covalent bond. …
How much can we extend the Finkelstein reaction?
May 25, 2023 · They need something like a silane to activate them because the Si–F bond is of a competitive strength. Yes, the Finkelstein can work in other solvents, especially with the correct …
halides - Why is fluorine more reactive than iodine despite the weaker ...
Silica is readily attacked by $\ce {HF}$ not because it is a strong acid, but rather because of the strength of $\ce {Si-F}$ bond thus formed. That deals with the thermodynamic parts of "reactivity", in the …
Is there any chemical that can destroy PTFE or Teflon?
Jul 20, 2015 · However, carbon-fluorine is second only to the Si-F bond. Is there an "overclocked" Teflon made of silicon-fluorine bonds that is even stronger? Now I know that some, but very few, solvents …
