A process in which a compound of one oxidation state changes to compounds two or more oxidation states

disproportionation

The process whereby a molecule is split into simpler fragments which may be smaller molecules, atoms, free radicals or ions.

dissociation

Some atoms can share two pairs of electrons to form a double bond (two covalent bonds).

double bond

Intensely coloured compounds applied to a substrate. Colours are due to the absorption of light to give electronic transitions.

dyestuffs

A conformation in which substituents on two attached saturated carbon atoms overlap when viewed as a Newman projection.

eclipsed

The tendency for atoms in a molecule to attract electrons

electronegativity

The particular order in which electrons are arranged in an atom or molecule.

electronic configuration

If an electron passes from one orbital to another an electronic transition occurs and there is the emission or absorption of energy corresponding to the difference in energy of the two orbitals known as

electronic transition

An atom, molecule or ion able to accept an electron pair.

electrophile

An overall reaction in which an electrophile binds to a substrate with the expulsion of another electrophile is known as

electrophilic substitution

A a substance which cannot be further subdivided by chemical methods.

element

A a pair of isomers which are related as mirror images of one another.

enantiomers

A graph of the energy of a reaction against the progress of the reaction.

energy diagram

A thermodynamic quantity which is a measure of the degree of disorder within any system.

entropy

A naturally occurring substance able to catalyse a chemical reaction.
