Key Concepts

Electrophile

An electrophile is a species that is electron-deficient and tends to accept an electron pair, making it susceptible to attack by electron-rich species. In reaction mechanisms, the electrophile plays a critical role by interacting with nucleophiles to form new chemical bonds.

Reaction Mechanism

A reaction mechanism describes the step-by-step sequence of elementary reactions by which overall chemical change occurs. It includes details of bond formation and bond breakage, the intermediates formed, and the movement of electrons throughout the reaction process.

Curved Arrow Notation

Curved arrow notation is a symbolic tool used to indicate the movement of electron pairs during a chemical reaction. The arrows start at an electron source, such as a lone pair or a ?-bond, and point to the electron-deficient site being attacked, thereby visually representing the mechanism.

Rate-Determining Step

The rate-determining step is the slowest step in a multi-step reaction mechanism, and it controls the overall reaction rate. This concept is essential for understanding reaction kinetics and for identifying which part of the mechanism may be targeted to accelerate the reaction.

Nucleophile

A nucleophile is a species that donates an electron pair to form a bond with an electrophile. Its electron-rich nature makes it reactive in many chemical mechanisms, particularly in those where it attacks electron-deficient centers to initiate bond formation.
