A reaction where an electron-rich species replaces a functional group in an electron-deficient molecule.

The nucleophile attacks the substrate (electron-deficient molecule) and forms a bond with it.

The principal product is the original molecule (R) now bonded to the nucleophile (Nuc): R-Nuc

The leaving group (LG) is the atom or group of atoms that departs from the substrate during the reaction.

A nucleophilic substitution reaction is a type of organic reaction where a nucleophile replaces a leaving group in a substrate.

The nucleophile plays a crucial role in a nucleophilic substitution reaction by donating an electron pair to form a new bond with the substrate.

The principal product of a nucleophilic substitution reaction is a new compound with a new bond between the substrate and the nucleophile.

Examples of nucleophiles in a nucleophilic substitution reaction include negatively charged species like Cl-, OH-, and CN-, as well as neutral species with a lone pair of electrons like NH3 and H2O.

The leaving group in a nucleophilic substitution reaction is a group that leaves the substrate, forming a new bond with the nucleophile, and is typically a stable molecule or ion with a weak bond to the substrate.
