Why FeCl3 is stable but FeI3 is unstable?
Table of Contents
Why FeCl3 is stable but FeI3 is unstable?
FeI3 is unstable because Fe^+3 is strong oxidising agent but I^- has very less reducing power.
Why is FeI3 not stable?
Why is FeI_(3) not stable? Due to more oxidising power of Fe3+ and less reducing power of I- .
Why is FeCl3 stable?
Iodide ion (I-) is a strong reducing agent and reduces Fe3+ ion to Fe2+ ion. On the other hand, chloride ion (Cl-) being a weak reducing agent cannot reduce Fe3+ ion. As a result, ferric chloride (FeCl3) is quite stable.
Is FeCl3 unstable?
FeCl3 is stable but FeI3 is unstable.
Why FeCl3 is more stable than fecl2?
The outermost electrons in 4s2 are readily given out to Chlorine. But it requires a further catalyst or oxidant like Oxygen or H2O2 etc, to give out an unpaired 3d^6 electron from d orbitals. In general , Ferric [ Fe (III) ] compounds are more stable as compared to Ferrous ( Fe (II) ) compounds.
Does FeI3 exist?
FeI3 does not exist. FeF3 is white solid inspite of five unpaired electrons with d5 congfiguration. FeCl3 is soluble in water and is used as a mordant in dyeing industry.
Is FeI3 a solid?
It is a thermodynamically unstable compound that is difficult to prepare….Iron(III) iodide.

Which is more stable fecl2 or FeCl3?
Explanation: The outermost electrons in 4s2 are readily given out to Chlorine. But it requires a further catalyst or oxidant like Oxygen or H2O2 etc, to give out an unpaired 3d^6 electron from d orbitals. In general , Ferric compounds are more stable as compared to Ferrous Fe compounds.
Which is the most stable compound among the following?
trans-1,2-cyclohexanediol.
Why is FeI2 formed instead of FeI3?
Why does iron react with iodine to form FeI2 not FeI3? – Quora. The short answer is that Iodine is not a sufficiently powerful oxidising agent to oxidise Iron to the level of III.
Why FeI3 does not exist in pure state?
I- reduces Fe3+ to Fe2+ and itself gets oxidised to I2, hence FeI3 is unstable. So, it being an oxidising agent oxidises Fe2+ to Fe3+, which favours formation of FeCl3 and makes it stable.
