Alkane[edit]

Mid-2006, this article failed the Good Article nomination. These are the comments:

  • WP:LEAD too short.
  • The names of all alkanes end with -ane. ... why? Talk about the history or where the nomenclature comes from.
  • Trivial names ... again why are these name kept or why do these compound have multiple names.
  • Images imbedded in text isn't recommended, plus they need to have captions.
  • Too many lists, at least in the beginning. - done -- Quantockgoblin 16:55, 8 February 2007 (UTC)[reply]
  • References missing. Use the Cite.php method if possible because it is recommended.. - done -- Quantockgoblin 21:33, 24 March 2007 (UTC)[reply]
  • The line, Alkanes occur both on Earth and in the solar system, however only the first hundred or so, and even then mostly only in traces., doesn't make any sense ... first hundred of what, alkanes, branched alkanes or unbranched alkanes.
  • methane and ethane are every day gases, at least methane is emitted by animals through their feces. That is much more relevant than knowing it is present on such comet that is not known to the general public.
  • On Titan, the satellite of Saturn, it is believed that there were once large oceans of these and longer chain alkanes: smaller seas of liquid ethane are thought still to exist there. - This is trivia or it pertains tu such articles as Titan or ethane.
  • ... produced primarily by forms of Archaea. - maybe should say ... produced primarily by organisms such as Archaea.
  • Although they cannot be commercially exploited at the present time, the calorific value of the known methane hydrate fields exceeds the energy content of all the natural gas and oil deposits put together—methane extracted from methane hydrate is considered therefore a candidate for future fuels. - This should not be in the occurence section but in the Properties section. - disagree; they are about occurence Rifleman 82 23:52, 5 February 2007 (UTC)[reply]
  • Occurence section and Alkanes in nature should be merged or be one under the other as they go toward a same goal, which is showing where these alkanes are present.
  • In the Occurence section, the Today, the most important commercial sources ... text and what comes after should go into a section that explains why do we have the alkanes on the earth like Earth's alkane and its sources or so. - I'd say it would belong in an article on crude oil or something similar. --Rifleman 82
  • ... within the individual fractions the boiling points lie closely together. - Some explanation on this point .would be greatly appreciated. - done -- Quantockgoblin 21:33, 24 March 2007 (UTC)[reply]
  • ... although the following demarcation is idealized and not perfect. - This statement is pov unless it is referenced or the word idealized is changed. I won't agree - Rifleman 82
  • The Preparation section is a bit short, needs images of the reactions or needs to be merged with the Purification section. - done -- Quantockgoblin 16:55, 8 February 2007 (UTC)[reply]
  • The reactions should be labeled with names or be traced back to the publications where they were taken from. - done -- Quantockgoblin 16:55, 8 February 2007 (UTC)[reply]
  • trim down on conformation as it is already covered in Alkane stereochemistry, same goes for reactions of alkanes. Also too many subheaders. - done -- Quantockgoblin 21:33, 24 March 2007 (UTC)[reply]


I think the unit in IR spectroscopy should be cm-1 (wavenumbers) not nm —Preceding unsigned comment added by 71.225.50.186 (talk) 05:48, 23 January 2008 (UTC)[reply]

I've striked out those points which have been fixed, though opinions may differ. It appears that much remains to be done. What other comments are there? --Rifleman 82 20:22, 5 February 2007 (UTC)[reply]

Viscosity of liquid alkanes could be added.--213.205.192.13 (talk) 01:27, 31 January 2016 (UTC)[reply]
