JEE Main 2013d and f Block Elements Question with Solution

JEE Main 2013 (07 Apr)

Question

Given

ECr3+/Cro=-0.74 V;  EMnO4-/Mn2+o=1.51V

ECr2O72-/Cr3+o=1.33 V;   ECl2|Cl-o=1.36V

Based on the data given above, strongest oxidising agent will be:

Choose an option

Correct answer
B MnO 4 -

Step-by-step explanation

Strongest oxidising agent has the highest tendency to get reduce therefore will have the highest standard reduction potential. So among the given oxidising agents the species have highest value of reduction potential is:
EMnO4-/Mn2+o=1.51V
