Encyclopedia > Addition reaction

An addition reaction, in chemistry, is in its simplest terms an organic reaction where two or more molecules combine to form a larger one. Chemistry (from Greek χημεία khemeia[1] meaning alchemy) is the science of matter at the atomic to molecular scale, dealing primarily with collections of atoms, such as molecules, crystals, and metals. ... Organic reactions are chemical reactions between organic compounds. ...


There are two main types of polar addition reactions:

Other non-polar addition reactions exists as well: In organic chemistry, an electrophilic addition reaction is an addition reaction where in chemical compound a pi bond is removed by the creation of two new covalent bonds. ... In organic chemistry, a nucleophilic addition reaction is an addition reaction where in a chemical compound a pi bond is removed by the creation of two new covalent bonds by the addition of a nucleophile. ...

Addition reactions are limited to chemical compounds that have multiply-bonded atoms: Free radical addition occurs when a peroxide is present in an alkene. ...

An addition reaction is the opposite of an elimination reaction. For instance the hydration reaction of an alkene and the dehydration of an alcohol are addition-elimination pairs. Covalent bonding is a form of chemical bonding characterized by the sharing of one or more pairs of electrons between atoms, in order to produce a mutual attraction, which holds the resultant molecule together. ... Covalent bonding is a form of chemical bonding characterized by the sharing of one or more pairs of electrons between atoms, in order to produce a mutual attraction, which holds the resultant molecule together. ... In organic chemistry a hetero atom refers to nitrogen, oxygen, sulfur, and the halogens. ... An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one or two-step mechanism. ... In organic chemistry, a hydration reaction is a chemical reaction in which a hydroxyl group (OH-) and a hydrogen cation (an acidic proton) are added to the two carbon atoms bonded together in the carbon-carbon double bond which makes up an alkene functional group. ... The chemical structure of ethylene, the simplest alkene. ... Functional group of an alcohol molecule. ...
