[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.
