Common Organic Functional Groups
Organic functional groups are atoms or groups of atoms that are attached to a carbon atom and give the molecule its characteristic chemical properties. Some of the most common functional groups include:
- Alkanes: CnH2n+2 (e.g., methane, ethane)
- Alkenes: CnH2n (e.g., ethylene, propene)
- Alkynes: CnH2n-2 (e.g., acetylene, propyne)
- Alcohols: ROH (e.g., methanol, ethanol)
- Aldehydes: RCHO (e.g., formaldehyde, acetaldehyde)
- Ketones: RCOR’ (e.g., acetone, butanone)
- Carboxylic acids: RCOOH (e.g., formic acid, acetic acid)
- Esters: RCOOR’ (e.g., methyl acetate, ethyl benzoate)
- Amides: RCONH2 (e.g., acetamide, benzamide)
- Amines: RNH2 (e.g., methylamine, ethylamine)
Organic Reaction Mechanisms
Organic reaction mechanisms are the step-by-step processes by which organic reactions occur. These mechanisms can be complex, but they can be understood by considering the following principles:
- The curly arrow mechanism shows the movement of electrons during a reaction.
- The rate-determining step is the slowest step in a reaction and determines the overall rate of the reaction.
- The Hammond postulate states that the transition state of a reaction resembles the structure of the product.
Stereochemistry
Stereochemistry is the study of the three-dimensional arrangement of atoms in molecules. Stereochemistry is important in organic chemistry because it can affect the physical and chemical properties of molecules.
- Enantiomers are molecules that are mirror images of each other.
- Diastereomers are molecules that are not mirror images of each other but have the same molecular formula.
- The Cahn-Ingold-Prelog (CIP) system is used to assign absolute configurations to chiral molecules.

Physical Chemistry
Physical chemistry delves into the macroscopic and microscopic properties of matter and how these properties are affected by changes in energy. It encompasses three fundamental concepts: thermodynamics, kinetics, and equilibrium.
Thermodynamics
Thermodynamics examines the relationships between heat, work, and energy in chemical systems.
- Enthalpy (H) measures the heat content of a system.
- Entropy (S) quantifies the randomness or disorder of a system.
- Gibbs Free Energy (G) determines the spontaneity of a reaction.
- ΔG = ΔH – TΔS
- A negative ΔG indicates a spontaneous reaction.
Kinetics
Kinetics focuses on the rates of chemical reactions.
Rate Law
rate = k[A]^m[B]^n
- k is the rate constant.
- [A] and [B] are the concentrations of reactants.
- m and n are the reaction orders.
Arrhenius Equation
k = Ae^(-Ea/RT)
- A is the pre-exponential factor.
- Ea is the activation energy.
- R is the gas constant.
- T is the temperature in Kelvin.
Equilibrium
Equilibrium occurs when the forward and reverse reaction rates are equal.
Equilibrium Constant (K)
K = [products]/[reactants]
- K is a constant for a given reaction at a specific temperature.
- A large K value indicates a reaction that favors products.
Le Chatelier’s Principle
Changes in reaction conditions shift the equilibrium to counteract the change.
