Q9 / 75 · JEE Main 2025 (3 Apr Shift 2) · Chemistry

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
  • Correct answer
    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

Solution

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.

Hence, the correct answer is option: 'B'.
