Organic ChemistryCannizzaro Reaction
The disproportionation of an aldehyde with no alpha hydrogen under concentrated alkali into an alcohol and a carboxylate.
Organic ChemistryChain Isomerism
Structural isomerism arising from different arrangements of the carbon skeleton.
Chemical Kinetics & CatalysisChain Reaction

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 Effect
The greater stability of a complex containing a multidentate ligand compared with one containing equivalent monodentate ligands.
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 & CatalysisChemisorption
Strong adsorption in which actual chemical bonds form between the adsorbate and the surface.
Chemical Kinetics & CatalysisCollision Frequency
The number of collisions occurring per unit volume per unit time in a reacting mixture.
States of Matter & Gas LawsCompressibility Factor
The ratio of the actual molar volume of a gas to that predicted by the ideal gas law.
States of Matter & Gas LawsCondensation
The change of a substance from the gaseous to the liquid state, accompanied by the release of latent heat.
Chemical Bonding & Molecular StructureCovalent Bond
A bond formed when two atoms share one or more pairs of electrons so that both achieve a stable configuration.
States of Matter & Gas LawsCritical Temperature
The temperature above which a gas cannot be liquefied by pressure alone, however great.
Solutions & Colligative PropertiesColligative Properties
Solution properties that depend only on the number of dissolved solute particles, not on their chemical identity.
