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

Options

  1. AN
  2. BAs
  3. CSb
  4. DBi

Correct answer

D. 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 , tendency to disproportionate decreases.
