Which among the following order of oxidising character is correct?
Options:
Answer:
A
Solution:
The correct option is (A) CrO₃ > MoO₃.
Group Trend: In transition metals, the stability of higher oxidation states increases down the group (from 3d to 4d to 5d).
Oxidizing Power: Since Mo(VI) in MoO₃ is more stable than Cr(VI) in CrO₃, CrO₃ has a stronger tendency to get reduced. Therefore, CrO₃ is a much stronger oxidizing agent than MoO₃.
Other options are incorrect because KMnO₄ is a stronger oxidizer than K₂Cr₂O₇, and higher oxidation states (V₂O₅) are more oxidizing than lower ones (V₂O₃).
