Welcome to the tag category page for Addition reaction!
A substitution reaction is a chemical reaction in which one atom or functional group in a molecule is replaced by another atom or group. In organic chemistry, these reactions are classified by the nature of the substituting reagent as electrophilic or nucleophilic, and by mechanism (such as SN1 or SN2). The process involves breaking the bond to the leaving group and forming a new bond to the incoming substituent.
