Question

Given below are two statements: Statement (I) : In the Lanthanoids, the formation of 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:

(A) Statement I is false but Statement II is true
(B) Both Statement I and Statement II are true
(C) Statement I is true but Statement II is false
(D) Both Statement I and Statement II are false

Prashant Kotian · Accepted Answer

Correct answer: B. Statement (1) is true, Ce+4 has noble gas electronic configuration. Statement (2) is also true due to high reduction potential for Ce4+/Ce3+ (+1.74V), and stability of Ce3+, Ce4+ acts as strong oxidizing agent.
