Summary
Alkyl/ Aryl halides may be classified as mono, di, or polyhalogen (tri-, tetra-, etc )
compounds depending on whether they contain one, two or more halogen atoms in
their structures Since halogen atoms are more electronegative than carbon, the carbon-
halogen bond of alkyl halide is polarised; the carbon atom bears a partial positive
charge, and the halogen atom bears a partial negative charge
