Given below are two statements: Statement I: CrO3 is a stronger oxidizing agent than MoO3. Statement II: Cr(VI) is more stable than Mo(VI) (In the light of the above statements, choose the correct answer from the options given below)

1. Statement I is true but Statement II is false
2. Statement I is false but Statement II is true
3. Both Statement I and Statement II are false
4. Both Statement I and Statement II are true

Correct answer: Statement I is true but Statement II is false

Solution

CrO3 is indeed a stronger oxidizing agent than MoO3 due to chromium's higher oxidation state and greater ability to accept electrons. However, Cr(VI) is less stable than Mo(VI) because chromium in this oxidation state is more prone to reduction, making Statement II false.
