Given below are two statements: Statement (I) : In the Lanthanoids, the formation Ce+4 is favoured by its noble gas configuration. Statement (II) : Ce+4 is a strong oxidant reverting to the common +3 state. In the light of the above statements, choose the most appropriate 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

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: Both Statement I and Statement II are true

Solution

Both statements are accurate; the formation of Ce+4 is indeed favored due to its noble gas configuration, and Ce+4 acts as a strong oxidant, readily reverting to the more stable +3 oxidation state.
