Study Notes
Branches of Organic Chemistry
- Structural Organic Chemistry: deals with the structure and bonding of organic molecules
- Physical Organic Chemistry: studies the physical properties and reactions of organic molecules
- Synthetic Organic Chemistry: focuses on the methods and strategies for synthesizing organic compounds
- Mechanistic Organic Chemistry: explores the mechanisms of organic reactions
Functional Groups
- A functional group is a specific group of atoms within a molecule that determines its chemical properties and reactivity
- Common functional groups:
- Alkyl (R-)
- Alkenyl (R-CH=CH-)
- Alkynyl (R-C≡C-)
- Hydroxyl (R-OH)
- Carbonyl (R-CO-R')
- Amino (R-NH2)
- Carboxyl (R-COOH)
IUPAC Nomenclature
- A system of rules for naming organic compounds
- Uses prefixes, suffixes, and root words to describe the structure of a molecule
- Examples:
- Methane (CH4)
- Ethanol (CH3CH2OH)
- But-2-ene (CH3CH=CHCH3)
Isomerism
- Structural Isomerism: different molecules with the same molecular formula
-
Stereoisomerism: different molecules with the same molecular formula and bond order, but differing in three-dimensional arrangement
- Enantiomers: non-superimposable mirror images
- Diastereomers: non-superimposable, non-mirror images
Reaction Mechanisms
- Substitution Reactions: replacement of a functional group with another
- Elimination Reactions: removal of a functional group, leading to a new π bond
- Addition Reactions: formation of a new bond between two molecules
- Rearrangement Reactions: reorganization of atoms within a molecule
Reaction Conditions
- Temperature: affects the rate and outcome of a reaction
- Solvents: influence the reaction rate and selectivity
- Catalysts: speed up reactions without being consumed
- Reagent: a substance that participates in a reaction
Important Concepts
- Acid-Base Chemistry: the study of proton transfer reactions
- Redox Reactions: oxidation and reduction reactions
- Stereochemistry: the three-dimensional arrangement of atoms in a molecule
- Resonance: the delocalization of electrons within a molecule
