Chemistry 3(carbon Chem) Flashcards
Fractional distillation works through what concept
Different condensation points of the different hydrocarbons
Hydrocarbons are made up of what two things
Hydrogen - carbon
Alkanes have what bonds
Single bonds
Alkenes have what bonds
Double
Saturated hydrocarbons have what bonds
Single covalent bonds
Unsaturated compounds have what bonds
Double bonds
Alkanes general formula
C(n)H(2n+2)
Alkene formula
C(n) H(2n)
Why are alkenes really reactive
High electron density in the double bond
Electrophiles are what?
Electron pair acceptors
Nucleophiles are what
Electron pair donors
What can you use to test for double bonds
What colour does it go
Orange Bromine water
Decolourises
What forms when ethene is added to bromine water
H2C=CH2 + Br2 -> CH2BrCH2Br
1,2-dibromoethane
Addition polymerisation is what
Process of adding lots of monomers like ethene together
What are the polymers structures affected by during polymerisation
Temperature and pressure
Poly ethene at 200*/2000 Pa
Flexible / low density
Polyethene at 60* /3Pa
Rigid and loose
2 examples of low density polyethene
Plastic bags
Squeeze bottles
Polypropene uses
Bottle crates
Rope
2 examples of high density poly(ethene)
Washing up liquids
Industrial packaging drums
PVC can be either (2)
Stretchy / rigid
2 uses of PVC
Window frames/piping
Synthetic leather
Polymers are not what…. hence why there’s an environment problem
Biodegradable
Complete combustion equation
Hydrocarbon + oxygen —> carbon dioxide +water +energy
