Study Notes

Nucleophilic Substitution Reaction

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

Nucleophile's Role

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

Principal Product

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

Nucleophile Examples

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.

Leaving Group

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.
