Organic ChemistryChain Isomerism
Structural isomerism arising from different arrangements of the carbon skeleton.
Chemical Kinetics & CatalysisChain Reaction
A self-sustaining reaction sequence in which a reactive intermediate regenerates itself at each cycle.
Atomic Structure & PeriodicityChalcogens
The group 16 elements — oxygen, sulfur, selenium, tellurium and polonium — collectively known as the ore-forming elements.
Inorganic & Coordination ChemistryCharge Transfer Spectrum
An intense absorption produced when an electron moves between metal and ligand orbitals.
States of Matter & Gas LawsCharles's Law
At constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature.
Inorganic & Coordination ChemistryChelate
A cyclic complex formed when a multidentate ligand grips a metal ion through two or more donor atoms.
Inorganic & Coordination ChemistryChelate Effect
The greater stability of a complex containing a multidentate ligand compared with one containing equivalent monodentate ligands.
Chemical Bonding & Molecular StructureChemical Bond
The attractive force that holds atoms or ions together in a stable chemical species.
Foundations of ChemistryChemical Change
A change in which the atoms of one or more substances are rearranged into new substances with different properties.
Stoichiometry & Chemical ReactionsChemical Equation
A symbolic representation of a chemical reaction showing reactants on the left and products on the right.
Chemical EquilibriumChemical Equilibrium
The state of a reversible reaction in which the forward and reverse reactions proceed at equal rates, so no net change in composition…
Foundations of ChemistryChemical Formula
A symbolic notation that states which elements a substance contains and in what proportions, using element symbols and subscripts.
Chemical Kinetics & CatalysisChemical Kinetics
The study of reaction rates, the factors that influence them, and the step-by-step mechanisms by which reactions occur.
Foundations of ChemistryChemical Property
A characteristic that describes how a substance transforms into a different substance, observable only during a chemical reaction.
Analytical Chemistry & SpectroscopyChemical Shift
The position of an NMR signal relative to a reference, expressed in parts per million of the operating frequency.

The one-, two- or three-letter abbreviation used internationally to represent an element.
Chemical Kinetics & CatalysisChemisorption
Strong adsorption in which actual chemical bonds form between the adsorbate and the surface.
Organic ChemistryChirality
The property of a molecule that makes it non-superimposable on its mirror image.
Analytical Chemistry & SpectroscopyChromatography
A family of separation techniques that partition components between a stationary and a mobile phase.
Analytical Chemistry & SpectroscopyChromophore
The part of a molecule responsible for absorbing light at a particular wavelength.
Thermochemistry & ThermodynamicsClosed System
A system that can exchange energy but not matter with its surroundings.
Nuclear & RadiochemistryCloud Chamber
A device that reveals the paths of ionising particles as visible trails of condensed vapour.
