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 :

Answer»

`Cr^(3+)`
`Cl^(-)`
Cr
`MN^(2+)`

Solution :(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.
