Substitution Reaction Definition

Definition: A substitution reaction is a type of chemical reaction where an atom or functional group of a molecule is replaced by another atom or functional group.

Examples: CH3Cl reacted with a hydroxy ion (OH-) will produce CH3OH and chlorine. This substitution reaction replaces the chlorine atom on the original molecule with the hydroxy ion.
