* [[Hans Christian Ørsted]] reduces [[aluminium chloride]] to produce metallic [[aluminium]] in an impure form.
* [[Friedrich Wöhler]] and [[Justus von Liebig]] perform the first confirmed discovery and explanation of [[isomers]], earlier named by Berzelius. Working with cyanic acid and fulminic acid, they correctly deduce that isomerism is caused by differing arrangements of atoms within a molecular structure.<ref name="CHF">{{cite web|url=https://www.sciencehistory.org/historical-profile/justus-von-liebig-and-friedrich-w%C3%B6hler|title=Justus von Liebig and Friedrich Wöhler|work=Science History Institute|date=June 2016}}</ref><ref name=Bowden>{{cite book|last1=Bowden|first1=Mary Ellen|title=Chemical achievers : the human face of the chemical sciences|url=https://archive.org/details/chemicalachiever0000bowd|url-access=registration|date=1997|publisher=Chemical Heritage Foundation|location=Philadelphia, PA|isbn=9780941901123|chapter=Justus von Liebig and Friedrich Wöhler|pages=[https://archive.org/details/chemicalachiever0000bowd/page/83 83–87]}}</ref>
