Given below are two statements : one is labelled as Statement I and the other is labelled as Statement II:

Statement I: CrO3\mathrm{CrO}_{3} is a stronger oxidizing agent than MoO3\mathrm{MoO}_{3}

Statement II: Cr(VI)\mathrm{Cr}(\mathrm{VI}) is more stable than Mo(VI)\mathrm{Mo}(\mathrm{VI})

In the light of the above statements, choose the correct answer from the options given below :

  1. Option A:

    Statement I is true but Statement II is false

    Correct
  2. Option B:

  3. Option C:

    Both Statement I and Statement II are false

  4. Option D:

    Both Statement I and Statement II are true

Answer: A

Step-by-step solution

Oxidising strength: CrO3>MoO3\mathrm{CrO}_{3}>\mathrm{MoO}_{3}

Stability : Cr6+<Mo6+\mathrm{Cr}^{6+}<\mathrm{Mo}^{6+}
