Question

Cerium (IV) has a noble gas configuration. Which of the following is correct statement about it? IV o 4+ 3+

(A) It will not prefer to undergo redox reactions.
(B) It will prefer to gain electron and act as an oxidizing agent
(C) It will prefer to give away an electron and behave as reducing agent
(D) It acts as both, oxidising and reducing agent.

Correct answer: B) IT WILL PREFER TO GAIN ELECTRON AND ACT AS AN OXIDIZING AGENT. Formation of Ce is favoured by its noble gas configuration but it is strong oxidant reverting to the +3 state. The E value for Ce /Ce is 1.74 V & is favourable for its oxidizing nature
