Given below are two statements :
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

Options

  1. AStatement I is false but Statement II is true
  2. BStatement I is true but Statement II is false
  3. CBoth Statement I and Statement II are true
  4. DBoth Statement I and Statement II are false

Correct answer

B. Statement I is true but Statement II is false

Step-by-step solution

Statement-I is true but statement II is false.
Cr(VI)\mathrm{Cr}(\mathrm{VI}) is less stable than Mo(VI)\mathrm{Mo}(\mathrm{VI})
Hence, CrO3\mathrm{CrO}_3 easily reduce into Cr+3\mathrm{Cr}^{+3} as compared to MoO3\mathrm{MoO}_3 and show stronger oxidizing nature.
