JEE Main2016Chemistryd and f Block ElementsActual

Find the metallic and ferromagnetic substance.

Options

  1. AV O 2
  2. BM n O 2
  3. CT i O 2
  4. DC r O 2

Correct answer

D. C r O 2

Step-by-step solution

In d-block elements, M n O 2 and CrO 2 exhibit strong attraction to magnetic fields and are able to retain their magnetic properties. MnO 2 is anti-ferromagnetic and CrO 2 is ferromagnetic.
