haloalkanes Flashcards
1
Q
define nucleophile
A
electron pair donator
2
Q
what is the reaction for haloalkanes?
A
nucleophilic substitution
3
Q
hydrolysis definition
A
breaking of bonds using water
4
Q
what happens to the rate of hydrolysis down the group?
A
- rate of hydrolysis increases
- as the strength of the carbon-haloalkane bond decreases
- so less energy required to break the bonds
5
Q
what happens to the rate of hydrolysis of primary, secondary and tertiary haloalkanes
A
- rate of hydrolysis increases
- as the number of steps in the mechanism increases
6
Q
how do CFCs deplete the ozone layer?
A
- breaks carbon- halogen bonds in CFCs by homolytic fission to form radicals
- this reacts with ozone and so breaks it down
7
Q
list 3 sources of CFCs in the atmosphere
A
- refrigerators
- air conditioners
- aerosols
