Class 12 Chemistry Haloalkanes and Haloarenes Nature of C-X Bond

Nature of C-X Bond

  • Halogen atoms being more electronegative than carbon possess a polarized bond between the carbon halogen of alkyl halide.
  • The carbon atom of the alkyl halide possesses a partial positive charge. The halogen atom on the other hand possesses a partial negative charge.

  • The carbon-halogen bond length increases from C—F to C—I due to the increase in the size of halogen atom while going down the group in a periodic table from fluorine to iodine atom.

  • Consequently the carbon-halogen bond length also increases from C—F to C—I.
