Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): In aqueous solutions  is reducing while  is oxidising in nature.

Reason (R): Extra stability to half filled electronic configuration is observed than incompletely filled electronic configuration.

In the light of the above statement, choose the most appropriate answer from the options given below:

Canvas Classes · Accepted Answer

Assertion (A):  is reducing;  is oxidising — TRUE ✓

-  () readily loses an electron to become  (, stable) → reducing agent
-  () readily gains an electron to become  (, half-filled stable) → oxidising agent

Reason (R): Half-filled configuration has extra stability over incompletely filled — TRUE ✓

Is R the correct explanation of A? YES ✓

-  () →  (): gains stability (not half-filled but  is stable due to exchange energy)
-  () →  (): gains half-filled stability → strong driving force to oxid
