Halogenalkane properties
C-X polar bond (x-/c+)

Dipole dipole and van der waal forces

Boiling points increase down group 7
1 of 5
Nucleophilic substitution
Requires a nucleophile
(:OH-, :NH3, :CN-, :NU-)

Nuclephile attacks slightly positive carbon and causes it to lose halogen
2 of 5
Elimination
Requires a secondary or tertiary halogenalkane, ethanol and a high temp & pressure

:OH- attacks the hydrogen then the electrons are transferred to they carbon forming a C=C bond and releasing the halogen
3 of 5
CFCs
ChloroFluoroCarbons

Decompose in the atmosphere via free radical substitution top remove ozone
4 of 5
CFCs reaction
C2F3Cl3 -> Cl’ + C2F3Cl2

O3 + Cl’ -> O2 + ClO’

ClO’ + Cl’ -> 2O2 + Cl’
