Study Notes
Organic Chemistry
-
Definition:
- Branch of chemistry focused on the study of carbon-containing compounds and their properties, structures, reactions, and synthesis.
-
Basic Structure of Organic Compounds:
-
Functional Groups:
- Distinct groups of atoms responsible for the characteristic reactions of a compound (e.g., -OH, -COOH, -NH2).
-
Hydrocarbons:
- Compounds composed solely of carbon and hydrogen. Types include:
- Alkanes (single bonds)
- Alkenes (at least one double bond)
- Alkynes (at least one triple bond)
- Compounds composed solely of carbon and hydrogen. Types include:
-
Functional Groups:
-
Isomerism:
- Structural Isomers: Different arrangements of atoms (e.g., butane vs. isobutane).
- Geometric Isomers: Different spatial arrangements (cis-trans).
- Enantiomers: Non-superimposable mirror images (chiral molecules).
-
Nomenclature:
- IUPAC naming system based on longest carbon chain, functional group priority, and substituents.
- Prefixes indicate number of carbon atoms (e.g., meth-, eth-, prop-).
-
Reactions:
- Addition Reactions: Typically involve alkenes and alkynes gaining atoms.
- Substitution Reactions: Replacement of one atom or group in a molecule.
- Elimination Reactions: Removing atoms to form a multiple bond or a ring.
- Rearrangement Reactions: Structural changes in the molecule.
-
Common Classes of Organic Compounds:
- Alcohols: Contain hydroxyl (-OH) group.
- Carboxylic Acids: Contain carboxyl (-COOH) group.
- Amines: Contain amino (-NH2) group.
- Esters: Formed from carboxylic acids and alcohols.
-
Key Concepts:
- Hybridization: Mixing of atomic orbitals (sp3, sp2, sp) to form new hybrid orbitals in the bonding process.
- Resonance: Delocalization of electrons in molecules that can be represented by multiple structures.
- Stereochemistry: Study of the spatial arrangement of atoms in molecules and its effect on chemical properties.
-
Applications:
- Pharmaceuticals: Design and synthesis of drugs.
- Biochemistry: Understanding metabolic pathways and biomolecules.
- Material Science: Development of polymers and new materials.
-
Techniques:
- Spectroscopy: Techniques like NMR, IR, and UV-Vis for structure determination.
- Chromatography: Method for separating and analyzing compounds in mixtures.
-
Safety and Practices:
- Awareness of organic solvents and reagents, handling procedures, and waste disposal.
