Web5.5 Fisher Projection. For the discussions so far, the perspective formula with solid and dashed wedges has been used to represent the 3D arrangement of groups bonded to a chirality center. In addition, there is … WebSupport. Organic compounds are chemicals based on carbon. They were given the name "organic" in 1807 by John Jakob Berzelius because these compounds that make life possible, e.g., carbohydrates, fats (lipids), proteins, and nucleic acids, were originally thought to be derived only from living organisms as opposed to those derived from …

The purpose of this lab was to separate heptane and hexane by fractional and simple . distillation. WebThe modern chemical definition of reduction is when a compound gains one or more electrons. It is therefore the opposite of oxidation, where a compound loses one or more electrons. One of the earliest named reactions featuring reduction is the Tishchenko reaction, named after the Russian organic chemist Vyacheslav Evgen'evich Tishchenko.
