Which one of the following statments about NO is wrong?

Options

  1. ANO is an odd electron molecule
  2. BIt is a free radical and highly reactive
  3. CIt readily forms complexes with transition metal ions
  4. DIt can be prepared by heating NH ₄ NO ₃ at 250^ C

Correct answer

D. It can be prepared by heating NH ₄ NO ₃ at 250^ C

Step-by-step solution

It can be prepared in the laboratory by reacting sodium, nitrite ( NaNO ₂ ) with a reducing agent such as Fe ²⁺ in an acidic medium. NH ₄ NO ₃ on heating at 250^ C gives N ₂ O .
