FeCl(3) is known but not Fel(3) Why?...

`FeCl_(3)` is known but not `Fel_(3)` Why?

Text Solution

Verified by Experts

`I^(-)` is a strong reducing agent, it reduces Fe3+ to `Fe^(2+) (or) Fe^(3+)` can oxidise I tol, but not `Cl^(-)` to `Cl_(2).2Fe^(3+)+2I^(-)rarr2Fe^(2)+I_(2)`. Thus `FeCl_(3)` is known but not `Fe_(3)`.
