Non-Polar Addition Reactions
Nonpolar addition reactions involves the addition of nonpolar molecules or nonpolar functional groups to unsaturated compounds in the absence of a polar solvent or catalyst. Non-polar addition reaction are further divided into two types which are:
- Free Radical Addition Reactions: Involves the addition of a free radical to a double bond.
- Cycloaddition Reactions: Involves the addition of two or more unsaturated molecules to form a cyclic product.
Free Radical Addition Reactions
Free radical addition reactions involve the addition of free radicals to unsaturated substrates, such as alkenes which result in formation of a new covalent bond.
One example of a radical addition reaction is the addition of hydrogen bromide (HBr) to an alkene in the presence of a peroxide initiator. This reaction results in the anti-Markovnikov addition of H and Br to the alkene, where the bromine ends up on the less substituted carbon of the alkene.
Cycloaddition Reactions
Cycloaddition reactions involve the formation of cyclic compounds from two or more reactants. These reactions are characterized by the formation of multiple new bonds and the creation of a cyclic structure in the product.
One example of a cycloaddition reaction is the Diels-Alder reaction, which consists of the reaction of a conjugated diene with a dienophile to form a cyclic compound. An example of this reaction is the reaction of 1,3-butadiene with ethene to form cyclohexene.
Addition Reaction
Addition reaction is a chemical process in which two or more molecules combine to form a single molecule. They are typical of unsaturated organic compounds such as alkenes, alkynes, aldehydes, and ketones.
In this article, we will look into what addition reaction is, types of addition reaction, its examples, applications, and the difference between addition and substitution reaction.
