2024 · 1 Feb · Shift 2 · Q13

JEE MainChemistryD and F Block ElementsMCQ+4 / −1
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : In aqueous solutions Cr2+\mathrm{Cr}^{2+}Cr2+ is reducing while Mn3+\mathrm{Mn}^{3+}Mn3+ 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 statements, choose the most appropriate answer from the options given below :
  1. A
    (A) is true but (R) is false
  2. B
    Both (A) and (R) are true and (R) is the correct explanation of (A)
  3. C
    Both (A) and (R) are true but (R) is not the correct explanation of (A)
  4. D
    (A) is false but (R) is true
