|
Alicyclic hydrocarbon
|
A chain of carbons in a ring like structure. e.g. Cyclohexanol.
|
|
|
Aliphatic hydrocarbon
|
A chain of carbon atoms where the structure is a simple un-branched chain or a branched chain.
|
|
|
Lone pair
|
A pair of electrons on the outer most shell that do not take part in chemical bonding.
|
|
|
Cis–trans isomerism
|
This is a special type of E/Z isomerism whereby there is a non-hydrogen atom and a hydrogen atom connected to one carbon atom this is connected to another by a double bond.
|
|
|
E/Z isomerism
|
A type of stereo-isomerism whereby the molecule has to indeed have a carbon to carbon double bond .Furthermore each of these carbon atoms has to be attached to two different groups. e.g. di-bromoethene
|
|
|
Hydrogen bond
|
A strong dipole to dipole attraction between a lone pair of electrons on a very electronegative atom and a electron deficient hydrogen atom
|
|
|
Intermolecular force
|
This is the attraction force between nearby molecules.
|
|
|
Stereoisomers
|
A stereo-isomer is an isomer with the atoms joined up in the same order but the atoms are in different arts of space from their original position.
|
|
|
Structural isomers
|
A molecule with the same number of atoms but a different chain length or structure. e.g. pentane can also be put down as methyl-butane
|
|
|
Van der Waals’ forces
|
A weak intermolecular attraction between small temporary dipoles in nearby molecules an example of this is the lattice in phosphorous which has a simple molecular structure.
|
|
|
Addition Polymer
|
This is a polymer molecule formed from an addition reaction such as when ethylene monomers come together to form polyethylene.
|
|
|
Addition Polymerisation
|
This is when unsaturated alkene monomers and on to an increasing polymer chain one at a time, to form a very long chain of monomers (Addition polymer)
|
|
|
Biodegradable material
|
This a material that will simply break down naturally after some time into compost.
|
|
|
Monomer
|
A small molecule that joins with other identical molecules in order to make a polymer. (e.g. ethylene)
|
|
|
Polymer
|
A large molecule chain that is built up of several identical monomers.
|
|
|
Repeat unit
|
A special arrangement of atoms that can be continually repeated because it has unfinished bonds on each side.
