Question

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

• A. Both Statement I and Statement II are false
• B. Statement I is true but Statement II is false
• C. Both Statement I and Statement II are true
• D. Statement I is false but Statement II is true

Answer 1

Answer: (C)

Both Statement I and Statement II are true

Answer 2

Statement I Explanation:

CrO₃ (chromium in +6 oxidation state) is a well-known strong oxidizing agent compared to MoO₃ due to its higher oxidizing potential. Therefore, Statement I is true.

Statement II Explanation:

Chromium(VI) compounds (e.g., CrO₃/dichromate) are kinetically and thermodynamically more stable in solution than the corresponding molybdenum(VI) species. Therefore, Statement II is true.

Both statements are correct.
