Key Areas in Organic Chemistry
1. Structure and Bonding
1. Structure and Bonding
- Carbon's Versatility: Forms single, double, and triple bonds, enabling chains, rings, and complex frameworks.
- Hybridization: sp³ (tetrahedral), sp² (planar), and sp (linear) hybridization.
- Functional Groups: Groups of atoms that define chemical properties (e.g., alcohols, aldehydes, ketones, carboxylic acids, amines).
2. Stereochemistry
- Isomerism:
- Structural Isomers: Same molecular formula, different connectivity.
- Stereoisomers: Different spatial arrangements.
- Enantiomers: Non-superimposable mirror images.
- Diastereomers: Not mirror images.
- Chirality: Importance in pharmaceuticals and biochemistry.
- Conformational Analysis: Rotation about single bonds (e.g., Newman projections, chair conformations).
3. Reaction Mechanisms
Organic reactions often follow predictable patterns involving:
Organic reactions often follow predictable patterns involving:
- Nucleophiles and Electrophiles: Electron donors and acceptors.
- Reaction Types:
- Substitution (SN1, SN2).
