As we learnt in

Ionization Enthalpies -

Due to increase in nuclear charge, there is in an increase in ionization Enthalpies from left to right with small variation.

 

-

 

 Order of second ionisation enthalpy is Cr>Fe>Mn>V


Option 1)

V

This option is incorrect.

Option 2)

Cr

This option is correct.

Option 3)

Mn

This option is incorrect.

Option 4)

Fe

This option is incorrect.
