Question:

Statement I: Number of Faraday’s required for the conversion of nitrobenzene to aniline is 8

Statement II: Change in oxidation number is 6

Options:

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I

Both Statement I and Statement II are correct and Statement II is not a correct explanation of Statement I

Statement I is correct but Statement II is false

Statement I is false but Statement II is correct

Correct Answer:

Statement I is false but Statement II is correct

Explanation:

The answer is 4. Statement I is false but Statement II is correct.

Statement I is false because the number of Faraday's required for the conversion of nitrobenzene to aniline is 6, not 8. This is because the oxidation number of nitrogen in nitrobenzene is +3, and the oxidation number of nitrogen in aniline is -1. Therefore, 6 electrons are required to reduce the nitrogen atom in nitrobenzene to aniline.

Statement II is correct because the change in oxidation number is 6. This is the number of electrons that are transferred during the reaction.
