1
A process in which a compound of one oxidation state changes to compounds two or more oxidation states
disproportionation
2
The process whereby a molecule is split into simpler fragments which may be smaller molecules, atoms, free radicals or ions.
dissociation
3
Some atoms can share two pairs of electrons to form a double bond (two covalent bonds).
double bond
4
Intensely coloured compounds applied to a substrate. Colours are due to the absorption of light to give electronic transitions.
dyestuffs
5
A conformation in which substituents on two attached saturated carbon atoms overlap when viewed as a Newman projection.
eclipsed
6
The tendency for atoms in a molecule to attract electrons
electronegativity
7
The particular order in which electrons are arranged in an atom or molecule.
electronic configuration
8
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
9
An atom, molecule or ion able to accept an electron pair.
electrophile
10
An overall reaction in which an electrophile binds to a substrate with the expulsion of another electrophile is known as
electrophilic substitution
11
A a substance which cannot be further subdivided by chemical methods.
element
12
A a pair of isomers which are related as mirror images of one another.
enantiomers
13
A graph of the energy of a reaction against the progress of the reaction.
energy diagram
14
A thermodynamic quantity which is a measure of the degree of disorder within any system.
entropy
15
A naturally occurring substance able to catalyse a chemical reaction.
enzyme
