Many chemical bonds are known to be polarisable. Similarly, many ions are also known to be polarisable. Examples include the carbon-iodine bond and the carbonate ion. Recently, I have read that the carbon-fluorine bond is, in fact, non-polarisable. Reasons for this include the high electronegativity of fluorine and the small sizes of the carbon and fluorine atoms.

  • Do other non-polarisable bonds exist?
  • What factors would contribute to a chemical bond being non-polarisable?

    $\begingroup$ Polarizability is a property of compounds. Bonds contribute to it relatively little. $\endgroup$ – Ivan Neretin Sep 27 '17 at 10:08
