Definition: What is Addition Reaction?
Addition reaction occurs when two or more reactants combine to form a product without the loss of any atoms present in the reactants. Addition reaction is common in compounds that have unsaturated C-C bond, like double (alkene) and triple (alkyne) bonds. The weaker π bond is converted into two new stronger σ bonds. Alkenes can give rise to a wide variety of products with various regioselectivity and stereoselectivity depending on the reagent and reaction conditions. There are typically two types of addition reactions – electrophilic addition and nucleophilic addition. Michael Addition is a type of nucleophilic addition reaction [1-4].
Examples of Addition Reaction
Alkyne can undergo addition reaction to give an alkene or its derivative.
Mechanism of Addition Reaction
The mechanisms of electrophilic and nucleophilic addition reactions proceed through intermediates.
