Q.
Given below are two statements:

Statement I: ${CrO}_{3}$ is a stronger oxidizing agent than ${MoO}_{3}$ .

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: [2025]

1 Statement I is false but Statement II is true.

2 Statement I is true but Statement II is false.

3 Both Statement I and Statement II are true.

4 Both Statement I and Statement II are false.

Ans.
(2)

In $d$ block, stability of higher oxidation state increases down the group. Thus Mo(VI) is more stable than Cr(VI). Thus ${CrO}_{3}$ is easily reduced to ${Cr}^{3 +}$ and is better reducing agent than ${MoO}_{3}$ .

Q. 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: [2025]

1 Statement I is false but Statement II is true.

2 Statement I is true but Statement II is false.

3 Both Statement I and Statement II are true.

4 Both Statement I and Statement II are false.

Ans. (2) In d block, stability of higher oxidation state increases down the group. Thus Mo(VI) is more stable than Cr(VI). Thus CrO3 is easily reduced to Cr3+ and is better reducing agent than MoO3.
