Organic Chemistry  The Chemistry of Carbon
Organic chemistry is the study of carbon-containing compounds  from simple hydrocarbons like methane to proteins, DNA and modern pharmaceuticals.
Key Topics
- Functional groups  alcohols, aldehydes, ketones, carboxylic acids, amines.
- Reaction mechanisms  substitution (SN1, SN2), elimination (E1, E2), addition.
- Stereochemistry  chirality, R/S configuration, enantiomers.
- Spectroscopy  NMR, IR, mass spectrometry.
Why It Matters
Every drug, polymer, fuel and biomolecule is an organic compound. Mastery of mechanisms lets you predict new chemistry rather than just memorise it.
