For which of the following elements it is difficult to disproportionate in +3 oxidation state?

Options

  1. AN\mathrm{N}
  2. BAs
  3. CSb\mathrm{Sb}
  4. DBi\mathrm{Bi}

Correct answer

D. Bi\mathrm{Bi}

Step-by-step solution

In nitrogen family, due to inert pair effect as the tendency to show +3 oxidation state increases down the group from As to Bi\mathrm{Bi}, tendency to disproportionate decreases.
