Study Notes
Chemical Reaction Principles
- The Arrhenius theory describes the relationship between the rate constant and the activation energy.
Structure and Reactivity
- The Hammond-Leffler postulate states that the structure of the reactants in a chemical reaction resembles the structure of the transition state leading to the major product.
Thermodynamic Feasibility
- The Gibbs free energy (ΔG) determines the feasibility of a reaction in terms of thermodynamics.
Kinetics
- Mechanistic kinetics focuses on the speed of a chemical process and the mechanism of the reaction.
Product Distribution
- The Curtin-Hammett principle describes the control exerted over the product distribution by the rate at which the products are formed.
Equilibrium
- The position of the equilibrium between two different chemical states is determined by the equilibrium constant (K).
Energetics in Organic Chemistry
- The concept of strain energy is important in understanding the energetics of molecules in organic chemistry.
Molecular Structure
- Cyclic molecules may exhibit long bonds, small rings, and large rotation barriers.
Thermodynamic Feasibility (Again)
- The Gibbs free energy (ΔG) determines the feasibility of a reaction in terms of thermodynamics.
Chemical Structure and Bonding
- Bonding is intimately related to structure in chemistry.
