Nature of Carbon-Halogen Bond in Haloalkane
Due to electronegative nature of halogens, electron density of carbon halogen bond slightly moves towards halogen side to give slightly negative charge on halogen and slightly position charge on carbon.
Hence C-Halogen bond is polar in nature.
- Size of halogen atom: I>Br>Cl>F
- Bond Length: I>Br>Cl>F
- Dipole Moment: Cl<F<Br<I
