2.2.2 Halogenoalkanes

HideShow resource information
What is hydrolysis?
splitting of a molecule by a substitution reaction with H2O
1 of 9
What is a nucleophile?
electron pair donor
2 of 9
Describe the rate of hydrolysis
water is a poor nucleophile // aqueous silver nitrate is added - faster the formation of the ppt, more reactive // the weaker the C-X bond the faster
3 of 9
What are the uses of halogenoalkenes?
chloro/ tetrafluroethene produce plastics PVC and PTFE
4 of 9
What are the uses of PVC?
insulation in electrical wires, windows - waterproof
5 of 9
What are the uses of PTFE?
chemical and heat resistive - cooking utensils
6 of 9
What are CFCs?
Chlorofluorocarbons
7 of 9
What are the uses of CFCs?
developed a sure in aerosols, refrigerants and air conditioning our to low reactivity, volatility and toxicity
8 of 9
Why are CFCs no longer used?
legislation banned usage / scientists discovered damaged ozone layer / ozone friendly alternative like hydrocarbons and HCFCs
