JEE Mains · Chemistry · STD 12 - 4. d and f- block elements
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 & Solution
Correct Answer
(B) Statement I is true but Statement II is false
Step-by-step Solution
Detailed explanation
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.
