Other Substances from Crude Oil
- Cracking
- the process of using heat to turn large
hydrocarbons into smaller, more useful
molecules
- the process of using heat to turn large
hydrocarbons into smaller, more useful
molecules
- Alkenes
- A group of unsaturated
hydrocarbons
- double bonds in alkenes
make them much more
reactive than alkanes
- this makes alkenes
extremely useful
- this makes alkenes
extremely useful
- double bonds in alkenes
make them much more
reactive than alkanes
- A group of unsaturated
hydrocarbons
- Unsaturated
- when hydrocarbons like alkenes
have a double bond and so have the
potential to bond with extra
hydrogen atoms
- when hydrocarbons like alkenes
have a double bond and so have the
potential to bond with extra
hydrogen atoms
- Bromine water
- used to test for
alkenes
- if hydrocarbon contains double
bonds then bromine water changes
from orange to colourless
- the more bromine water used the
more double bonds in the chemical
- the more bromine water used the
more double bonds in the chemical
- if hydrocarbon contains double
bonds then bromine water changes
from orange to colourless
- used to test for
alkenes
- Monomers
- Polymers
- Polymerisation
- chemical reaction that changes
monomers to polymers
- chemical reaction that changes
monomers to polymers
- Smart polymers
- polymers that may have properties
changed by light, temperature of by
other changes in their surroundings
- polymers that may have properties
changed by light, temperature of by
other changes in their surroundings
- a long molecule made of lots
of monomers joined together
- Polymerisation
- small molecules
- Polymers
- Biodegradable plastics
- plastic made with corn starch
that will break down naturally
- plastic made with corn starch
that will break down naturally
