What Is a List of Organic Chemistry Reactions?


Quick Answer

Common organic chemistry reactions include elimination, hydration, SN1 substitution, SN2 substitution and reduction. Elimination reactions include reactions that result in the loss of a molecule to form new substances. Elimination reactions are common in alkene formation and occur in one or two steps. Dehydrohalogenation and dehydration are the most common forms of elimination reactions

A hydration reaction adds water to unsaturated substrates, such as alkenes or alkynes, to form new substrates. Acid-catalyzed hydration increases the rate of the reaction to form a diol by losing a hydrogen ion. Hydration reactions can also occur using bases and alcohols.

SN1 substitution reactions are unimolecular nucleophilic reactions in which an electron donor and an electron acceptor exchange an electron pair to form a new substrate. The electron acceptor has a leaving group that is displaced when the substitution occurs. SN1 reactions occur in two steps.

SN2 substitution reactions are bimolecular nucleophilic reactions that occur in a single step. One bond is broken and another bond is formed to create a new substrate. Usually, halides are involved in this type of reaction.

Reduction reactions increase the number of hydrogen atoms on a substrate. Often, a metal is used to break the double or triple bonds that allow the hydrogen to attach to the substrate. Reduction of an alkyl group forms an alkene.
