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
