Statement-1 : `Ce^(4+)` is more stable than `Ce^(3+)`.
Statement-2 : `Ce^(4+)` has noble gas configuration.

Statement-1 : Ce^(3+) cannot be easily oxidised to Ce^(4+) . Statement-2 : Ce^(3+) tends to lose its only 1 electron from 4f orbitals.

Ce^(4+) is stable .This is because of

Given below are two statements : Statement 1: The E value for Ce ^(4+) //Ce ^(2+) is + 1.74V. Statement II: Ce is more stable in Ce^(4+) state than Ce^(3+) state In the light of the above statements, choose the most appropriate answer from the options given below:
