In group 15 elements which element show a fractional oxidation state?

Options

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

Correct answer

A. N

Step-by-step solution

In group number 15 elements shows -III and III oxidation state (by gain or loss of three p electrons). These shows V oxidation state due to loss of n p^3+n s^2 electrons. But nitrogen is unique in having a large number of oxidation states including a fractional one (i.e., - 1 3 in . N ₃ H )
