|
Chain Isomers |
Same functional group but different arrangements of the carbon skeleton |
|
|
Position isomers |
Have the same skeleton but groups of atoms are attached to different carbon atoms |
|
|
Functional group isomers |
Same atoms but different functional group |
|
|
Stereoisomers |
Same structural formula but their atoms are arranged differently in space. |
|
|
How does fractional distillation work? |
Crude oil is vaporised into a fractionating column. Temperature gradient in column 1 rises. Gases condense at different levels. Gases removed from top of the column. |
|
|
Geometrical isomers |
It is a form of stereoisomerism. Same definition |
|
|
Testing for unsaturation |
Shake the alkene with bromine water. Turns orange to colourless |
|
|
What is addition polymerisation |
Where alkenes:-(monomers:-) are substituted to form long polymers |
|
|
Nucleophillic reactions |
An electron pair donor |
|
|
Electrophile |
Electron pair acceptor |
|
|
What are plasticisers |
They are molecules which modify properties of polymers. They reduce the strength of intermolecular forces. |
|
|
Alkene uses |
To make plastics |
|
|
Molecular formula |
Gives the actual number of atoms of each element in a molecule |
|
|
Structural Formula |
Shows the atoms carbon by carbon |
|
|
Displayed formula |
Shows how atoms are arranged and all the bonds between them |
