Organic chemistry is the branch of chemistry that deals with the study of carbon-containing compounds. These compounds are essential to life and are found in all living organisms. Organic chemistry focuses on the structure, properties, and reactions of these compounds, as well as the synthesis and design of new organic molecules.
Organic chemistry plays a crucial role in various fields such as medicine, agriculture, and materials science. It is used to develop new drugs, pesticides, and materials, as well as to understand biological processes at the molecular level.
Some key concepts in organic chemistry include functional groups, isomerism, stereochemistry, and reaction mechanisms. Organic chemists use a variety of techniques and tools, such as spectroscopy, chromatography, and computational methods, to study and manipulate organic molecules.
Overall, organic chemistry is a diverse and dynamic field that continues to make significant contributions to science and technology.

Organic Chemistry
Definition: The study of compounds containing carbon and hydrogen, and their reactions and properties.
Key Concepts:
1. Structure and Bonding: - Covalent bonding between carbon atoms forms the backbone of organic molecules. - Hybridization of carbon orbitals determines molecular shape and reactivity.
2. Functional Groups: - Groups of atoms that impart characteristic properties to organic molecules. - Common functional groups include alkanes, alkenes, alkynes, alcohols, ketones, and acids.
3. Reactions: - Organic molecules undergo a wide variety of reactions, including: - Addition - Substitution - Elimination - Rearrangement
4. Stereochemistry: - The study of the three-dimensional arrangement of atoms in molecules. - Enantiomers are mirror images of each other and have different biological activities.
5. Spectroscopy: - Techniques used to analyze the structure and properties of organic molecules. - Common methods include nuclear magnetic resonance (NMR) and infrared spectroscopy (IR).
Applications:
- Pharmaceuticals: Synthesis and development of drugs to treat diseases. - Materials Science: Production of plastics, polymers, and composites. - Agriculture: Pesticides, herbicides, and fertilizers to improve crop yields. - Energy: Biofuels and renewable energy sources. - Environmental Science: Detection and remediation of pollutants.
History:
- Organic chemistry emerged as a distinct field in the early 19th century. - Friedrich Wöhler's synthesis of urea from inorganic starting materials in 1828 challenged the vital force theory. - Jöns Jakob Berzelius introduced the term "organic chemistry" in 1807.
Important Scientists:
- Friedrich Wöhler - Jöns Jakob Berzelius - Alexander Butlerov - August Kekulé - Johannes Brønsted - Thomas Midgley Jr. - Robert Burns Woodward
