Substitution Reaction
What is Substitution Reaction?
A substitution reaction is a type of organic reaction in which one atom or group of atoms in a molecule is replaced by another atom or group. In nucleophilic substitution (SN1 and SN2), a nucleophile replaces a leaving group. In electrophilic aromatic substitution, an electrophile replaces a hydrogen on a benzene ring. Halogenation of alkanes by free radical mechanism is also a substitution reaction.
