Alkene properties

CnH2n

Unsaturated hydrocarbons - turn bromine water colourless

C=C bond with pi bond that doesn’t rotate

No polar bonds so only van der waal

1 of 7

Monomer

Single group of small alkene chain

2 of 7

Polymer

Lots of monomers together forms repeating units

3 of 7

Addition polymers

Alkene has its C=C bond broken to form a repeating unit

4 of 7

Electrophilic addition

Requires an alkene and an electrophile
(Br2, HBr, H2SO4, H2O with catalyst)

5 of 7

Electrophilic addition mechanism

The C=C bond is attracted to the partially positive part of the electrophile

The C=C bond breaks and forms two carbon cations

The first part of the electrophile is attracted to the least stable carbon cation

The other part is attracted to the more st

6 of 7

E-Z isomers

Formed because of the pi bonds on C=C bonds that stop it rotating
