Organic Chemistry

Definition and Scope

• Organic chemistry is the study of carbon-containing compounds and their properties, reactions, and synthesis.
• It encompasses a vast range of compounds, including biomolecules, fuels, plastics, and pharmaceuticals.

Characteristics of Organic Compounds

• Typically contain carbon and hydrogen atoms, with other elements such as oxygen, nitrogen, and sulfur.
• Have covalent bonds between atoms, rather than ionic bonds.
• Can be found in solid, liquid, or gaseous states.

Functional Groups

• A functional group is a specific group of atoms within a molecule that determines its chemical properties.
• Examples of functional groups include:
  • Hydroxyl (-OH)
  • Carboxyl (-COOH)
  • Amino (-NH2)
  • Aldehyde (-CHO)
  • Ketone (-CO-)

Types of Organic Compounds

• Hydrocarbons: contain only carbon and hydrogen atoms.
  • Saturated hydrocarbons (e.g., methane, CH4)
  • Unsaturated hydrocarbons (e.g., ethene, C2H4)
• Aliphatic compounds: open-chain hydrocarbons.
• Aromatic compounds: ring-shaped hydrocarbons (e.g., benzene, C6H6).
• Heterocyclic compounds: contain atoms other than carbon and hydrogen in the ring structure.

Reactions in Organic Chemistry

• Substitution reactions: replacement of one functional group with another.
• Elimination reactions: removal of a functional group, resulting in a new π bond.
• Addition reactions: formation of a new bond between two molecules.
• Oxidation and reduction reactions: gain or loss of electrons.

Isomerism

• Isomers are molecules with the same molecular formula but different structures.
• Types of isomerism:
  • Structural isomerism: different bond connectivity.
  • Stereoisomerism: different 3D arrangements of atoms in space.

Synthetic Methods

• Laboratory methods for synthesizing organic compounds:
  • Grignard reaction
  • Friedel-Crafts reaction
  • Diels-Alder reaction
  • Williamson ether synthesis

Importance of Organic Chemistry

• Applications in:
  • Pharmaceuticals
  • Petrochemicals
  • Biotechnology
  • Materials science
  • Environmental science
