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. WebFischer Projections. Fisher projections show sugars in their open chain form. In a Fischer projection, the carbon atoms of a sugar molecule are connected vertically by solid lines, while carbon- oxygen and carbon-hydrogen bonds are shown horizontally. Stereochemical information is conveyed by a simple rule: vertical bonds point into the plane ...
