Reactivity of Molecules Reaction Mechanism topics include: Inductive, electromeric and mesomeric effect, hyperconjugation, carbocations and carbanions, nucleophillic and electrophilic substitution reactions.

In chemistry, a reaction mechanism is a theoretical description of the steps involved in a chemical reaction. It explains the order in which molecules react, and describes the bonds that are broken and formed. 

Reactivity is the impulse that causes a chemical substance to react, either by itself or with other substances. It involves thermodynamic and kinetic factors, which are both dependent on temperature. Reactivity refers to the rate at which a chemical substance reacts. 

The four main reaction mechanisms are:
Nucleophilic attack
Loss of the leaving group
Deprotonation
Carbocation rearrangement 

Reactive molecules share electrons to become more stable. Arrows are used to show the direction of the electrons. Each attacking arrow represents two electrons being shared.
