When I2 and FeCl2 are mixed together, iodine (I) cannot replace chlorine (Cl) in the compound because iodine is lower on the periodic table.

true/false

The given statement is True.

This is single replacement reaction.

As reactivity decreases down the group,

Iodine is less reactive than Chlorine.

And so Iodine cannot replace chlorine from FeCl2.

I2 + FeCl2 - --> no reaction (Iodine is less reactive than chlorine)

yes the answer is true
