Chemistry Overview and Physical Chemistry

Study Notes

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.
