Organic Mechanisms (A Level only) (AQA A-Level Chemistry): Flashcards

Sequence of steps transforming reactants into products

Show movement of electron pairs in mechanisms

Bond breaks evenly, each atom gets one electron

Bond breaks unevenly, both electrons to one atom

Species with unpaired electron, highly reactive

Represents movement of single electron

Represents movement of electron pair

One atom or group replaced by another

Two reactants combine to form single product

Small molecule removed, forms double bond
