I did, but fe and cr both have 4 unpaired electrons, how do i pick the more stable one from the two?
So there are two ways to look at it.
M/M2+ potential OR
M3+/M2+ potential
actually just gotta see data. Hard to do from theory.
the easy way out is that M2+ will be the most stable
Mn2+
ohh I see, I don't remember the exact data but should I be memorising it? all i remember is that cu has a positive M/M2+ and the first 3 elements have a negative M3+/M2+
See here you can figure out by the extreemes ie manganese
and generally, anything in ncert is fair game for neet or jee main
one can just choose to skip the q too 😄
but mad theory qs are more or less rank differentiators top 500 odd ranks me
ohhhh I see, thank you!
Thermal decomposition of AgNO3 produces two paramagnetic gases. The total no. of electrons present in the antibonding molecular orbitals of the gas that has the higher no. of unpaired electrons is:-
hey this a intext question in d & f ncert. I think cr3+ would be more stable than fe3+ due to half filled t2g of cr3+ , even though fe3+ has d5 extra stable configuration.

Hey thanks
