Results for “Mole”
18 terms
Acid Strength and Molecular Structure
The structural factors that determine how readily a molecule releases a proton.
Chemical Bonding & Molecular StructureAntibonding Molecular Orbital
A molecular orbital higher in energy than its parent atomic orbitals, whose occupation destabilises the molecule.
Chemical Kinetics & CatalysisActive Site
The specific region of a catalyst or enzyme at which the reacting molecules bind and are transformed.
Stoichiometry & Chemical ReactionsAddition Reaction
A reaction in which two molecules combine to form a single larger product, with no atoms left over.
Chemical Kinetics & CatalysisAdsorption
The accumulation of molecules of a gas or liquid on the surface of a solid.
Foundations of ChemistryAnion
A negatively charged ion produced when an atom or molecule gains one or more electrons.
Organic ChemistryAromaticity
The special stability of planar cyclic molecules with a continuous, fully conjugated system of delocalised pi electrons.
Solutions & Colligative PropertiesAssociation
The joining of solute molecules in solution into larger aggregates, reducing the effective number of particles.
Foundations of ChemistryAtomicity
The number of atoms present in one molecule of an element.
States of Matter & Gas LawsAvogadro's Law
Equal volumes of all gases at the same temperature and pressure contain equal numbers of molecules.
Foundations of ChemistryAvogadro's Number
The number of elementary entities in one mole of substance, fixed by definition at 6.02214076 × 10²³ mol⁻¹.
Solutions & Colligative PropertiesAbnormal Molar Mass
A molar mass value obtained from colligative measurements that differs from the true value because the solute associates or dissociates.
Organic ChemistryAldol Condensation
The base-catalysed reaction of two carbonyl compounds to give a beta-hydroxy carbonyl, which often dehydrates to an enone.
Acids, Bases & SaltsAmphoteric Substance
A substance able to react as either an acid or a base depending on what it meets.
Chemical EquilibriumAssociation Constant
The equilibrium constant for the combination of two species into a single associated entity, the reciprocal of the dissociation constant.
Foundations of ChemistryAtomic Mass Unit
A mass unit defined as exactly one twelfth the mass of a free, unbound carbon-12 atom in its ground state.
Atomic Structure & PeriodicityAtomic Orbital
A mathematical function describing the region around a nucleus where an electron of given energy is most likely to be found.
States of Matter & Gas LawsAverage Kinetic Energy
The mean translational kinetic energy of the particles in a sample, dependent only on absolute temperature.
