Critical Temperature
The temperature above which a gas cannot be liquefied by pressure alone, however great.
States of Matter & Gas LawsDalton's Law of Partial Pressures
The total pressure of a gas mixture equals the sum of the pressures each component would exert alone in the same volume.
Organic ChemistryDiastereomer
A stereoisomer that is not a mirror image of the compound with which it is compared.
Solutions & Colligative PropertiesDilution
The process of reducing a solution's concentration by adding more solvent, leaving the amount of solute unchanged.
Biochemistry & Polymer ChemistryDisaccharide
A carbohydrate formed when two monosaccharide units join through a glycosidic bond.
Chemical EquilibriumDistribution Law
The principle that a solute distributes itself between two immiscible solvents in a constant ratio at fixed temperature.
Chemical EquilibriumEffect of an Inert Gas
The influence of adding a non-reacting gas on the position of a gaseous equilibrium.
Chemical EquilibriumEffect of Pressure Change
The shift in a gaseous equilibrium caused by changing the total pressure through a volume change.
Chemical Bonding & Molecular StructureElectron Domain Geometry
The spatial arrangement of all electron domains — bonding and lone pairs alike — around a central atom.
Organic ChemistryElectrophile
An electron-deficient species that seeks and accepts a pair of electrons from an electron-rich centre.
Analytical Chemistry & SpectroscopyElectrophoresis
A separation technique in which charged species migrate through a medium under an applied electric field.
Chemical Kinetics & CatalysisElementary Reaction
A reaction that occurs in a single step exactly as written, with no detectable intermediate.
Foundations of ChemistryEmpirical Formula
The chemical formula giving the simplest whole-number ratio of atoms of each element in a compound.
Thermochemistry & ThermodynamicsEntropy
A measure of the dispersal of energy and the number of microscopic arrangements available to a system.
Foundations of ChemistryFormula Unit
The simplest whole-number ratio of ions represented in the empirical formula of an ionic or network compound.
Organic ChemistryFunctional Group Isomerism
Structural isomerism in which compounds of the same formula contain entirely different functional groups.
States of Matter & Gas LawsGaseous State
The state of matter in which particles are widely separated and move randomly at high speed, filling any container completely.
Stoichiometry & Chemical ReactionsGay-Lussac's Law of Combining Volumes
The principle that gases react in volume ratios that are simple whole numbers, when measured at the same temperature and pressure.
States of Matter & Gas LawsGay-Lussac's Pressure Law
At constant volume, the pressure of a fixed mass of gas is directly proportional to its absolute temperature.
Biochemistry & Polymer ChemistryGlucose
The most abundant monosaccharide and the primary energy source for most living cells.
States of Matter & Gas LawsGraham's Law of Diffusion
The rate at which a gas diffuses or effuses is inversely proportional to the square root of its molar mass.
Atomic Structure & PeriodicityHalogens
The group 17 elements — fluorine through astatine — which are one electron short of a full outer shell.
Thermochemistry & ThermodynamicsHeat Capacity at Constant Volume
The heat needed to raise a system's temperature by one kelvin while its volume is held fixed.
Chemical Kinetics & CatalysisHomogeneous Catalysis
Catalysis in which the catalyst is in the same phase as the reactants.
