20.1: Oxidation-Reduction Reactions of Organic Compounds
Synthetic organic chemists have a wide range of reagents at their disposal for the reduction or oxidation of functional groups in organic meaning that reduction of an asymmetrical ketone will result in a racemic mix of both R and S alcohols (recall from section 11.3 that aldehydes in aqueous solution exist in rapid equilibrium with

PDF fileSection 20.1 The Meaning of Oxidation and Reduction 633 Electron Shift in Redox Reactions The modern concepts of oxidation and reduction have been extended to include many reactions that do not even involve oxygen. You learned in Chapter 6 that, with the exception of ﬂu-orine, oxygen is the most electronegative element. As a result, when oxygen
20.1: Oxidation States & REDOX Reactions - Chemistry
The reduced half gains electrons and the oxidation number decreases, while the oxidized half loses electrons and the oxidation number increases. Simple ways to remember this include the mnemonic devices OIL RIG, meaning "oxidation is loss" and "reduction is gain," and LEO says GER, meaning "loss of e-= oxidation" and "gain of e-= reduced."
what is the exact meaning of oxidation state?
An increase in oxidation state is associated with oxidation (loss of electrons) while a decrease is associated with reduction (gain of electrons). There are multiple sets of rules how to assign oxidation states to atoms (see for example section on oxidation reduction reactions here or what to do for organic molecules here ).
