Chemistry Overview and Physical Chemistry

Chemistry Overview

• Chemistry is the scientific study of matter, its properties, composition, and behaviour.
• It encompasses various sub-disciplines, including physical, inorganic, organic, and analytical chemistry.
• Chemistry explores the structure of atoms, molecules, and the interactions between them.
• It uses the scientific method to develop theories and laws to explain observations.
• Foundational to many fields, like biology, medicine, materials science, and engineering.

Physical Chemistry

• Focuses on the theoretical foundation of chemistry, exploring the physical properties of chemicals.
• Concerned with the relationship between macroscopic properties and molecular behaviour.
• Covers areas such as thermodynamics, kinetics, electrochemistry, and spectroscopy.
• Key concepts include:
  • Thermodynamics: Studies energy changes in chemical and physical processes, including enthalpy, entropy, and Gibbs free energy.
  • Kinetics: Investigates the rates of chemical reactions and the factors affecting those rates.
  • Spectroscopy: Uses electromagnetic radiation to study molecular and atomic structure and properties.
  • Electrochemistry: Explores chemical reactions involving electron transfer and the properties of electrochemical cells.
• Uses mathematical models and equations to predict and explain phenomena.

Inorganic Chemistry

• Deals with the synthesis, structure, and properties of inorganic compounds.
• These include compounds not containing significant amounts of carbon.
• Focuses largely on metals and their compounds, and on non-metals.
• Studies the arrangement of electrons in atoms and molecules.
• Investigates the periodic table's trends and patterns of chemical behaviours.
• Includes the study of coordination compounds, transition metals, and main group elements.
• Includes studies of inorganic materials like minerals and ceramics.

Organic Chemistry

• Examines the structure, properties, composition, reactions and preparation of organic compounds.
• Organic compounds are essentially carbon-based compounds and their myriad combinations.
• Focuses on carbon's unique ability to form long chains, rings, and complex structures.
• Includes the study of functional groups, isomers, and reaction mechanisms.
• Explores classes of organic compounds such as alkanes, alkenes, alcohols, etc.
• Has very broad applications in various fields, including pharmaceuticals, polymers, and materials science.
• Organic chemistry is often divided into various sub-fields such as:
  • Stereochemistry: Explores the spatial arrangements of atoms in molecules.
  • Spectroscopy: Uses spectroscopic techniques to identify and characterize organic molecules.
  • Synthetic Organic Chemistry: Focuses on the creation and design of organic molecules.
  • Natural Product Chemistry: Studies biologically active molecules found in nature.
