Given : E(Cl(2)//Cl^(-))^(@)=1.36" V ...

Given :
`E_(Cl_(2)//Cl^(-))^(@)=1.36" V ", E_(Cr^(3+)//Cr)^(@)=0.74V`.
`E_(Cr_(2)O_(7)^(2-)//Cr^(3+))^(@)=1.33" V ", E_(MnO_(4)^(-)//Mn^(2+))^(@)=1.51" V"`.
Among the following, the strongest reducing agent is :

A

`Cr^(3+)`

B

`Cl^(-)`

C

Cr

D

`Mn^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) More negative the `E_(value)^(@)`, stronger is the reducing agent. In this case `E_(Cr^(3+)//Cr)^(@)=-0.74" V"`. Therefore, Cr is the stronger reducing agent.
