There is sp-sp hybrid orbital overlap to form double bonds
Double bonds are not always sp2 hybridized. In CO2 the C atom is sp hybridized.--G.Kiruthikan (talk) 05:39, 6 June 2014 (UTC)
The π contribution in sulfoxides, sulfones and most other sulphur–oxygen compounds is neglegible to nonexistant
This page propagates an outdated concept which has pretty much been refuted by computational chemistry research: the existance of so-called S–O ‘double bonds’. Their existance is pretty much limited to the sulphur oxides SO, SO2 and SO3. In practically all other cases, a charge separation model is much closer to the actual observed reality (in spite of what Pauling claimed without evidence). Note that none of these models require the high-energy virtual sulphur d orbitals to take part in bonding (which they don’t).
Thus, the page should be rewritten to state that most S–O bonds are not double bonds, why that is so and why they were historically thought to be ones. Unfortunately, the task is too tedious for me to perform right now. — 130.54.130.242 (talk) 03:36, 12 April 2018 (UTC)
Activated double bond redirection
Why does activated double bond redirect to an article having no information on this subtopic? A new section on activation would be welcome. (a section dealing with Meerwein reaction of diazonium compounds) uses the concept of activated double bonds, the only expalnation being an example involving a double bond which it thus implies to be activated).150.227.15.253 (talk) 10:12, 7 February 2020 (UTC)
consider combining "the double bond between atoms" section with double bond rule
