Which of the following statements is false about interhalogen compounds?

Options

  1. AThey are covalent in nature.
  2. BThey are diamagnetic.
  3. CThey are more reactive than halogens.
  4. DIf these are represented as XX ^1 , number of X ^1 atoms is always even .

Correct answer

D. If these are represented as XX ^1 , number of X ^1 atoms is always even .

Step-by-step solution

Interhalogen compounds ( XX'_n ) are covalent and diamagnetic due to paired electrons. They demonstrate greater reactivity than elemental halogens because their polar bonds are more susceptible to attack. The general formula permits n values of 1, 3, 5, or 7, all odd. Since the statement claims the number of X' atoms is always even, it is false. D
