Option 1

 * Carbon Dioxide Hydrogenation
 * (To create)
 * Article Evaluation
 * There is currently no article on CO2 hydrogenation. Reduction is an important process for the fixation and conversion of CO2 to more useful chemical precursors, and a large amount of research has been done on the process.

Option 2

 * Transition metal carbene complex:
 * Article Evaluation:The article is very bare-bones, only stating the types of carbenes and giving little explanation on their reactivity. There is a link to the Fisher carbene page, but there is no schrock carbene page, therefore I think this page should give a much better and more in-depth description of their bonding and reactivity. Furthermore, the Schrock carbene section has no references. :Also, the Applications section is poorly-cited, and contains information that is either wrong, or very poorly worded and misleading, especially in the first paragraph.:The discussion seems is relatively old and most of the discussion is on the NHC part of the article specifically.
 * Sources:The main sources given seem to be mostly good, including well-regarded textbooks and important articles, I plan on using mostly the same sources.

Option 3

 * Delta bond:
 * Article Evaluation:The lead paragraph gives a correct first approach to the topic, however it seems over-cited, with 4 textbook citations that most likely repeat the same information. Most of the rest of the article is then uncited, until the brief historical overview. I think the core of the article would benefit from being expanded, for example by giving more examples and MO explanations of δ-bonds, while also adding more citations and from more specific sources than only textbooks. The history section gives a brief overview of the history and is well-cited, but more information could be given about other molecules than [Re2Cl8]2-, like U2 which also exibit high bond-order bonding.:In the talk page, there was discussion of merging this article with the quadruple bond article, however it seems that the consensus was that it was preferred to keep them separate. Therefore, I think some of the concepts mentioned in the quadruple bond article should be re-iterated, or it should at least be talked about and linked.
