Study Notes
Overview of Organic Chemistry
- Branch of chemistry that studies the structure, properties, composition, reactions, and synthesis of carbon-containing compounds.
- Primarily involves compounds with carbon-hydrogen (C-H) bonds.
Key Concepts
-
Hydrocarbons
- Compounds composed solely of carbon and hydrogen.
- Types:
- Alkanes: Saturated hydrocarbons (single bonds; e.g., methane).
- Alkenes: Unsaturated hydrocarbons (at least one double bond; e.g., ethylene).
- Alkynes: Unsaturated hydrocarbons (at least one triple bond; e.g., acetylene).
-
Functional Groups
- Specific groups of atoms within molecules that determine the characteristics and reactions of those molecules.
- Common functional groups:
- Hydroxyl (-OH): Alcohols
- Carbonyl (C=O): Aldehydes and ketones
- Carboxyl (-COOH): Carboxylic acids
- Amino (-NH2): Amines
- Ester (-COO-): Esters
-
Isomerism
- Compounds with the same molecular formula but different structures.
- Types:
- Structural isomers: Different connectivity of atoms.
- Stereoisomers: Same connectivity but differ in spatial arrangement (cis-trans isomerism, enantiomers).
-
Reactions
- Organic reactions can be categorized based on the type of reactants and products:
- Addition reactions: Atoms are added to a double or triple bond.
- Elimination reactions: Atoms are removed, forming double or triple bonds.
- Substitution reactions: An atom or group is replaced by another atom or group.
- Rearrangement reactions: Atoms are rearranged to form a different compound.
- Organic reactions can be categorized based on the type of reactants and products:
-
Nomenclature
- Systematic naming of organic compounds based on IUPAC rules.
- Basic steps:
- Identify the longest carbon chain.
- Number the chain to give substituents the lowest possible numbers.
- Name the substituents and combine with the name of the main chain.
-
Synthesis and Mechanisms
- Study of how organic reactions occur, including reaction pathways and intermediates.
- Mechanisms often illustrate the movement of electrons (curly arrows).
-
Biomolecules
- Organic compounds that are vital for life.
- Categories:
- Carbohydrates: Sugars and starches.
- Proteins: Polymers of amino acids.
- Lipids: Fats and oils.
- Nucleic acids: DNA and RNA.
Applications of Organic Chemistry
- Pharmaceuticals: Development of medication and therapeutic agents.
- Agriculture: Creation of pesticides and fertilizers.
- Materials: Production of plastics, polymers, and industrial chemicals.
- Biochemistry: Understanding biological processes at a molecular level.
