Organic synthesis is a branch of chemical synthesis concerned with the construction of organic compounds. Organic compounds are molecules consisting of combinations of covalently-linked hydrogen, carbon, oxygen, and nitrogen atoms. Within the general subject of organic synthesis, there are many different types of synthetic routes that can be ...

Syn and anti addition. In organic chemistry, syn- and anti-addition are different ways in which substituent molecules can be added to an alkene (R2C=CR2) or alkyne (RC≡CR). The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.
Increasingly, LibreTexts topics are being cited in articles, at least in the chemistry project. It is a favorite for students doing homework. The articles in LibreTexts lack references, as far as I can see. I doubt that these references are reliable.
This is a starting point for collating free, web-based resources available to editors, as well as indexes to help point to sources. Please feel free to add new resources with a URL to the site, and a brief description. Don't worry too much about presentation or organization, this is just a draft. Add new headings as needed.
