This article desperately need expansion. Especially since it's such an important topic in MO theory.--Rejnal 06:10, 29 December 2006 (UTC)
- Agreed. The entire article, at this point, could be summed up as: Pi bonds are pi bonds. It is only informative if you were unaware of the existance of pi bonding to begin with. There is nothing here that would help someone understand why and how pi bonding occurs. --Matt D (talk) 09:37, 22 October 2008 (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.
