Halogenoalkanes Flashcards
Other than chain length, what affects the boiling point of a haloalkane?
Halogen atom - going down the group increases b.p. and m.p.
Why are haloalkanes not soluble in water?
The polar C-X bonds are not polar enough.
What is elimination?
A reaction in which an atom or group of atoms is removed from a reactant.
What is a nucleophile?
An ion or group of atoms with a negative charge or a partially negatively-charged area, with a lone pair of electrons, that takes part in an organic reaction by attacking an electron-deficient area in another reactant.
What do Halogenoalkanes have a polar bond?
The halogens are significantly more electronegative than carbon.
What conditions favour a substitution reaction?
Cold OH- in water.
What conditions favour an elimination reaction?
Hot OH- in ethanol.
What are chlorofluorocarbons?
Halogenoalkanes containing both chlorine and fluorine atoms but no hydrogen.
