- A \( \mathrm{SiO}_{2} \)
- B \( \mathrm{MgO} \)
- C \( \mathrm{SO}_{2}(\mathrm{~s}) \)
- D \( \mathrm{CrO}_{2} \)
Answer & Solution
Correct Answer
(D) \( \mathrm{CrO}_{2} \)
Step-by-step Solution
Detailed explanation
Few transition metal oxides show marked differences inelectrical properties, for example: \( \mathrm{TiO}, \mathrm{CrO}_{2} \) and \( \mathrm{ReO}_{3} \) behave
