What is Nucleophilic substitution?
A '''nucleophilic substitution''' is a [[chemical reaction]]. It is a type of [[substitution reaction|substitution]], or replacing, reaction. It happens when one [[nucleophile]] replaces another one on an [[atom]]. The other group leaves the atom and is called a [[leaving group]].<ref>J. March, ''Advanced Organic Chemistry'', 4th ed., Wiley, New York, 1992.</ref> There are different types of nucleophilic substitution. Which type happens depends on the type of the atoms and molecules involved. The two main categories of nucleophilic substitution are the [[SN1 reaction]] and the [[SN2 reaction]]. == References == <references/> {{Reaction mechanisms}} [[Category:Chemical reactions]] {{chem-stub}}
