Reactivity of Aryl Halides in a Substitution Reaction
Substitution reaction is a type of reaction where one of the groups in the substrate gets replaced by an incoming group introduced into the medium.
It can be either nucleophilic (attacked by a nucleophile) or electrophilic (attacked by an electrophile). Also, the mechanism via which the reaction occurs can be different depending on a lot of factors like substrate used, reagent used, the solvent medium.
Thus, the reactivity of all substrates are not equal but vary according to their nature for a fixed reagent and solvent medium.
