In which of the following compounds, an element exhibits two different oxidation states?

Options

  1. ANH ₄ NO ₃
  2. BN ₂ H ₄
  3. CN ₃ H
  4. DNH ₂ CONH ₂

Correct answer

A. NH ₄ NO ₃

Step-by-step solution

In NH ₄ NO ₃, ~N exhibits two different oxidation states. Actually NH ₄ NO ₃ exists as NH ₄⁺ and NO ₃⁻ . Oxidation state of N in ₄⁺ is -3 and in NO ₃⁻ is +5 .
