Interaction of sigma bond electrons with an empty p-orbital

Hi,

in the article it is mentioned that the p-orbital is an "antibonding" one. In my opinion, the lonely and empty p-orbital, e. g. in a carbenium ion, is "non-bonding", because there is no interaction with other pi-orbitals (e. g. creating a double bond).

Second, the description of the hyperconjugation effect as it is done in the first paragraph of the article is solely dedicated to stabilization effects in carbeniums atoms or the beta-silicon effect (and comparable situattions with a positive formal charge). For the explanation of the anomeric effect (and also the alpha-silicon-effect) we do not have an empty p-orbital, but have a "filled non-bonding hybrid-orbital (e. g. lone pairs at oxygen) or p-orbital (e. g. carbanions)" which is stabilized by an "empty antibonding sigma(asterisk)-orbital" in the neighbourhood.

I've changed the text slightly to mention that the p orbital is nonbonding. Feel free to correct the article, this is a wiki after all. Itub 22:46, 28 September 2006 (UTC)

External doesnt work

But I found this one instead: http://www.princeton.edu/~dmacgr/grpmtgs/2003/hyperconjugation.pdf is that the same pdf? ChristianB (talk) 03:07, 28 November 2007 (UTC)

• if a link goes dead just remove it. If you find another link with info of interest then include it. V8rik (talk) 17:45, 28 November 2007 (UTC)

Aren't these things similar? - No, they are not. Check http://en.wikipedia.org/wiki/Hypervalent.

Why is hyperconjugation called no bind resonance? Umer ilyas shaaheen (talk) 16:25, 26 January 2020 (UTC)
