Interhalogen compounds are formed when two halogens $(\mathrm{F}, \mathrm{Cl}, \mathrm{Br}, \mathrm{I})$ react together. They are represented by $\mathrm{XX}_n^{\prime}$, where X is halogen of larger size and $\mathrm{X}^{\prime}$ of smaller size. The total number of halogens in $\mathrm{XX}_n^{\prime}$ depends on the radii of X and $\mathrm{X}^{\prime}$. The correct statement(s) regarding $\mathrm{XX}_n^{\prime}$ is/are

• Correct answer
  A

  Halide ions reacts with interhalogen compounds to give polyhalides.
• Correct answer
  B

  Interhalogen compounds are covalent in nature and more reactive than halogens, in general.
• Correct answer
  C

  Iodine can form an interhalogen compound containing maximum numbers of halogen atoms.
• D

  $\mathrm{FCl}_3$ is one of the stable interhalogen compounds.

Hence, the correct answer is options: 'A', 'B', 'C'.
