[edit] Expansion
This article desperately need expansion. Especially since it's such an important topic in MO theory.--Rejnal 06:10, 29 December 2006 (UTC)
[edit] Double bonds
Since when are double bonds weaker than single bonds?
pi bond is weaker, double bond is stronger: two different things
[edit] Misleading statement?
"Atoms with double bonds or triple bonds usually have one sigma bond and the rest are usually pi bonds"
Surely this is not the case; carbonyl carbon with three sigma and one pi, carbon of ethene with three sigma and one pi.....or is something else intended by the statement?
- I suspect it means that in a multiple-bond between two atoms, one of those bonds is σ and the rest are π, which is a generally reasonable explanation for most people for most compounds. DMacks 21:14, 16 November 2006 (UTC)
Perhaps a rephrasing is in order; along the lines of "a multiple bond between two atoms usually consists of one sigma bond together with one or more pi bonds" ?
It's referring to within that one double or triple bond. It could be misread quite easily though, perhaps the wording should be different.
- I reworded the sentence, no longer misleading V8rik 18:17, 23 February 2007 (UTC)
