MCQ
Given below are two statements :
Statement I : $\mathrm{CrO}_{3}$ is a stronger oxidizing agent than $\mathrm{MoO}_{3}$
Statement II : $\mathrm{Cr}(\mathrm{VI})$ is more stable than $\mathrm{Mo}(\mathrm{VI})$
In the light of the above statements, choose the correct answer from the options given below
  • A
    Statement I is false but Statement II is true
  • B
    Statement I is true but Statement II is false
  • C
    Both Statement I and Statement II are true
  • D
    Both Statement I and Statement II are false

Answer

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