Discuss the physical properties of haloalkanes .

Explanation

Physical properties of halo alkanes :
1) Pure alkyl halides are colourless . Bromides and iodides exhibits colour when exposed to light .
2) Most of volatile halogen compounds have sweet smell .
3) Lower members of alkyl halides are gases and higher members are liquids (or ) solids .
4) The boiling points of chlorides , bromides and iodides are higher than those of hydrocarbons.
5) The boiling points of alkyl halides decrease as follows `RI gt RBr gt RCl gt RF`.
6) In case of isomeric halo alkanes boiling points decrease with increase in branching .
7) The density of halo alkane increase with increase in no. of carbon atoms , halogen atoms and atomic mass of the halogen atoms .
8) Halo alkanes have the tendency to dissolve in organic solvents and are very slightly soluble in water .
