formation of alkanes
halogens react with alkanes
1 of 12
structure of halogens
they are more lectro negative than carbon do they are polar the halogen is dekta negative and carbon is dlta posituve
2 of 12
describe hydrolysis and neclohhilpci substituion
halogenic alkanes can be hydrolised in water, neocluphile attacks the delta positive carbon and a lone pair of electrins is dontaed and pond is formes with the arbin and an halide ion is produces
3 of 12
test for halogens
when halide ion is produced in hydrolisis, it can be dected when adding aqueous naoh, then adding scidified silver nitrate
4 of 12
what colour does chloring bromie and iodine go when added to acidified silver nitrate
chlorine, white bromine cream idodine yellow
5 of 12
solubiliy of halogenic alkanes
they do not form on o-h bind therefor ethey cant dissolve however they bonf with nin polar molecules
6 of 12
what are used in fire extinguishers
tretrochloro methan ccl4
7 of 12
what is used in refrigortators
cfcs chlorofloro carbon
8 of 12
what is found in propellent
cfcs chlorofloro carbon
9 of 12
enviromenatl effct fo cfcs
radical reactions damgeing o zone layer letting uv light pass through and causing skin cancer
10 of 12
cfcs radiacls initiation
cond fission between the cl and c biond as it os the weakest and is caused by uv raditaion cfcl3 = cl* cfcl2
11 of 12
propiagtion of cfcs
the radicals break down the ozone layers CL* +O3 = CLO2*
