`(At. Nos. Cr = 24, Mn = 25, Fe = 26, Co = 27)`

A

`Cr gt Mn gt Co gt Fe `

B

`Mn gt Fe gt Cr gt Co`

C

`Fe gt Mn gt Co gt Cr`

D

`Co gt Mn gt Fe gt Cr`

Text Solution

Verified by Experts

The correct Answer is:
B
On the basis of electrode potentials, the correct order is `Mn gt Fe gt Cr gt Co`.
