Talk:Xenon hexafluoride

Untitled
Shouldn't the article read 3F2(g) and not 3F6(g)??? --ELiTe185 16:18, 11 September 2006 (UTC)


 * It should be HF. Obviously it doesn't produce fluorine gas; I don't think anything can produce F2 except electrolysis. —Keenan Pepper 21:50, 10 September 2006 (UTC)


 * Thanks, I understand now. --ELiTe185 16:19, 11 September 2006 (UTC)


 * Oh cool, looks like it is possible to prepare F2 chemically: Fluorine. XeF6 doesn't do it though. —Keenan Pepper 21:53, 10 September 2006 (UTC)

Indeed. Changed this. 128.226.130.90 (talk) 22:13, 24 July 2009 (UTC)

What about XeF8 ? http://www.nature.com/nchem/journal/vaop/ncurrent/abs/nchem.724.html —Preceding unsigned comment added by 212.110.168.191 (talk) 10:03, 5 July 2010 (UTC)

I think that Xenon hexafluoride has "pentagon piramidal" shape. Grozec (talk) 10:30, 17 March 2012 (UTC)

Nickel fluoride
Does the nickel fluoride covering the reaction container have a catalytic effect on the XeFn synthesis or not? The descriptions in the articles of the different xenon fluorides are contradictory concerning this topic. --79.243.233.166 (talk) 19:08, 4 September 2013 (UTC)

Enthalpy of Formation
There is a discrepancy between the enthalpy of formation reported in the literature.

The currently listed (on this wiki page) H_f is 294 kJ/mol

This article:

The enthalpies of formation of XeF6(c), XeF4(c), XeF2(c), and PF3(g) The Journal of Chemical Thermodynamics, Volume 4, Issue 6, November 1972, Pages 879–891

lists the H_f as ΔH_f(XeF6, g) = −(66.69 ± 0.61) kcal_th mol^−1

which is about equal to -279.031 kJ/mol

Which H_f should be used in this instance? — Preceding unsigned comment added by SolipsisticAltruist (talk • contribs) 14:15, 12 February 2014 (UTC)

Additionally, on page 497 in the book "Introduction to Modern Inorganic Chemistry, 6th edition", found here:

http://books.google.com/books?id=STxHXRR4VKIC&pg=PA497&lpg=PA497&dq=heat+of+formation+of+xenon+trioxide&source=bl&ots=EF4sIFa7SW&sig=7OHQPlzWzZDmxtUAixLuEYy_UVI&hl=en&sa=X&ei=X4f7Up2YEOazyAHwqYDACw&ved=0CG4Q6AEwCA#v=onepage&q=heat%20of%20formation%20of%20xenon%20trioxide&f=false

An exothermic heat of formation value of -335 kJ/mol is listed for XeF6.SolipsisticAltruist (talk) 14:48, 12 February 2014 (UTC)

Problem with first sentence.
This is currently the first sentence of the article:

"Xenon hexafluoride is a noble gas compound with the formula XeF6 and the highest of the three known binary fluorides of xenon, the other two being XeF2 and XeF4..."

I am not a chemist, and perhaps this makes sense to chemist. But I am reasonably well-educated and I have no idea what the word "highest" means here.

(It sounds as though xenon hexafluoride is more intoxicated with cannabis than the other two known binary fluorides of xenon.)

The word "high" has many meanings, but almost no Wikipedia reader will have any idea what is meant in this article. Can someone knowledgeable on this subject please rewrite that sentence so that it makes sense to more people? Thanks.2600:1700:E1C0:F340:B0EB:FCD2:CEF4:AE8A (talk) 05:42, 1 June 2019 (UTC)


 * An afterthought: Perhaps "highest" here means "heaviest"? If so, then whoever wrote that sentence should definitely improve their English language skills prior to contributing to the English-language edition Wikipedia in the future.2600:1700:E1C0:F340:B0EB:FCD2:CEF4:AE8A (talk) 05:45, 1 June 2019 (UTC)
 * Perhaps it meant highest amount of fluorine? That's how I read it, although it's still a weird way to say it I think. Maybe it's not that weird since I'm not really a chemist either JGHFunRun (talk) 18:35, 29 May 2022 (UTC)

Does it melt/boil or sublime?!
Now I don't have the qualifications to say which it does but I do know that it doesn't do _both_ since that's impossible, at least under the same conditions. In "It is a colorless solid that readily sublimes into intensely yellow vapors." But then the sidebar says it melts at 49.25 °C and boils at 75.6 °C. Which is it?!

Maybe it sublimes at room temp but at high temperatures it melts and at then boils? JGHFunRun (talk) 18:41, 29 May 2022 (UTC)


 * So apparently Wikipedia doesn't support italics using the markdown notation of _italics_. I shall remember that then JGHFunRun (talk) 18:42, 29 May 2022 (UTC)
