Biochemistry & Polymer ChemistryGlycosidic Bond
The covalent linkage joining a sugar unit to another molecule through an oxygen bridge.
Nuclear & RadiochemistryGray
The SI unit of absorbed radiation dose, equal to one joule of energy deposited per kilogram of matter.
Organic ChemistryHaloalkane
An alkane in which one or more hydrogen atoms have been replaced by halogen atoms.
Atomic Structure & PeriodicityHalogens
The group 17 elements — fluorine through astatine — which are one electron short of a full outer shell.
Chemical Bonding & Molecular StructureHOMO and LUMO
The highest occupied and lowest unoccupied molecular orbitals, which together govern a molecule's reactivity and spectroscopy.
Foundations of ChemistryHomogeneous Mixture
A mixture whose composition and properties are uniform throughout, with no visible boundary between the components.
Organic ChemistryHomologous Series
A family of compounds sharing the same functional group and general formula, with successive members differing by CH₂.
Organic ChemistryHydrocarbon
A compound composed exclusively of carbon and hydrogen.
Organic ChemistryHyperconjugation
The stabilising delocalisation of electrons from a sigma C–H bond into an adjacent empty or partly filled p orbital.
Chemical Kinetics & CatalysisInstantaneous Rate
The rate of a reaction at one particular moment, given by the gradient of the concentration–time curve at that point.
Chemical EquilibriumIonic Equilibrium
An equilibrium involving ions in solution, such as the dissociation of weak electrolytes or the dissolution of sparingly soluble salts.
Acids, Bases & SaltsIonic Product of Water
The equilibrium constant for the self-ionisation of water, equal to the product of the hydrogen and hydroxide ion concentrations.
Nuclear & RadiochemistryIonising Radiation
Radiation with enough energy to remove electrons from atoms, creating ions.
Chemical Bonding & Molecular StructureIon–Dipole Interaction
The attraction between an ion and the oppositely charged end of a polar molecule.
Thermochemistry & ThermodynamicsIsobaric Process
A process carried out at constant pressure.
Inorganic & Coordination ChemistryIUPAC Nomenclature of Complexes
The systematic rules for naming coordination compounds unambiguously.
Organic ChemistryKetone
A compound containing a carbonyl group bonded to two carbon atoms.
States of Matter & Gas LawsLatent Heat
The energy absorbed or released when a substance changes state, with no accompanying change in temperature.
Inorganic & Coordination ChemistryLigand Field Theory
The refined bonding model that combines crystal field theory with molecular orbital treatment of metal–ligand covalency.
Biochemistry & Polymer ChemistryLipid
A biomolecule that is largely non-polar and therefore insoluble in water but soluble in organic solvents.
States of Matter & Gas LawsLiquid Crystal
A state of matter that flows like a liquid but retains some of the molecular ordering of a crystal.
Chemical Bonding & Molecular StructureLone Pair
A pair of valence electrons localised on one atom and not involved in bonding.
