What is a Halogen?
An alkane skeleton with one or more halogens in the place of a hydrogen atom.
General formula: CnH2n+1X
(X is the halogen)
Melting and Boiling Points
As the chain length increases so does the melting and boiling points.
M.P. and B.P. increase down the group.
Increased Van Der Waals -> beacuse they are a larger molecule, more electrons etc.
Insolube: C-X bond isn't polar enough to make it soluble.
Main intermolectular forces:
- Van Der Waals,
- Dipole Dipole
- Dry cleaning fluids, when mixed with hydrocarbons.
Somethings gotta give...
When Haloalkanes react it is usually the C-X bond that will breaks
