Why can chlorine oxidise Fe2+ to Fe3+?

Why can chlorine oxidise Fe2+ to Fe3+?

It is a good oxidising agent. Iron(II) ions are easily oxidised to iron(III) ions, and iron(III) ions are fairly easily reduced to iron(II) ions. That means that Fe3+ ions don’t pick up electrons as easily as chlorine does. Chlorine is a stronger oxidising agent than Fe3+ ions.

Why fecl3 is more stable than fecl2?

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.

Why is FeCl3 stable?

Fe+3 is 3d5. 3d5 is half filled d subshell , hence stability adds. So , Fe +3 is more stable. In FeCl3 ,, Fe is +3 which means 3d5 system.

Why is FeI3 not stable?

Answer. I- is much larger in size, so has higher tendency to lose electron, and hence is a good reducing agent. 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.

Is FeI3 possible?

FeI3 does not exist because: | Chemistry Questions.

Does fef2 exist?

Iron(II) fluoride or ferrous fluoride is an inorganic compound with the molecular formula FeF2. It forms a tetrahydrate FeF2·4H2O that is often referred to by the same names.

Why FeI2 is formed rather than FeI3?

Large anions diminish the lattice energy of the higher halide to such an extent that the higher halide may be thermodynamically unstable. Iodide ion is a good reducing agent and hence reduces metal in higher oxidation state into lower Ones. Even, more interesting is the fact that FeI3 is extremely photosensitive!
