Addition reaction
From Wikipedia, the free encyclopedia
An addition reaction, in chemistry, is in its simplest terms an organic reaction where two or more molecules combine to form a larger one.
There are two main types of polar addition reactions:
Other non-polar addition reactions exists as well:
Addition reactions are limited to chemical compounds that have multiply-bonded atoms:
- Molecules with carbon-carbon double bonds or triple bonds
- Molecules with carbon - hetero double bonds like C=O or C=N
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.
- Addition reactions are applied in addition polymerization.
- halogenation
- hydration
- hydrohalogenation
- hydrogenation
