15 Haloalkanes Flashcards
(7 cards)
What are the 3 ways of making haloalkanes?
Free radical substitution
Electrophillic addition
Halide substitution of an alcohol
What intermolecular forces do haloalkanes use?
Idd
Pdd
How does the shielding of the halide in the haloalkane affect the polarity and hence the reactivity of the molecule?
Less shielding the more polar the molecule
What is a nucleophile?
A substance that donates electrons
Why does iodomethane react faster than chloromethane?
More sheilding in iodine
Weaker bond
How does NH3 react with bromomethane?
NH3 replaces Br but doesn’t fit so kicks off a hydrogen
Left over hydrogen and bromine join another NH3 to make NH4Br
What are cfc’s and how did they impact the ozone layer?
CFC- Chloroflurocarbons
Under UV from the sun they form radicals and react with ozone (O3) to continue to form radicals
