You are right.
Fe being in +1 state should have 5 unpaired electrons (4s1 3d6)
But nowadays it is being said that fe is in +3 state so only 3 unpaired electrons .
How? I mean why +3 @Azimuddin_Sheikh
Fe in +3 with NO-
Earlier it was believed to be Fe+ and NO+
I think they proved it using magnetic moment calculation itself
Didi i read that in wikipedia . but now also we r not confirmed about +3 also @Viraam_Rao. But as my sir told to do it with +3 so I did with +3
I think it’s proven now bro.
The second post has some research paper reference
But JEE wont ask such controversial question and that too for Mains.
If Fe is in +3 oxidation state how 3 unpaired electrons?? Shouldn't it be 5?
NO- is strong ligand.
But H20 is weak field ryt?? Nd agar pairing takes place so shouldn't it be 1 unpaired electrons then? @Viraam_Rao
So for jee adv, it's +3 right? @Viraam_Rao
Thx for that info , so we r given right info when it was not actually proven before .
I’m not sure what to take for advanced cuz in some 90s paper they took it as +1
I just hope they don’t ask about it
Does NCERT specifically say it’s +1 Fe ?
Yeah bro. I don’t think they asked after that. But at that time everyone thought it’s +1 so maybe now they’ll change.
They also follow ncert in ncert its +1
Bro still not getting how 3 unpaired? If it's strong field then pairing occurs. Then 1 unpaired electron?
@Viraam_Rao bro don't consider from 1990s paper , check it from 2008 onwards
Actually just follow NCERT then
Iske solution mein bhi Fe+ diya hai but don't know how 3 unpaired electrons in this as well
Yeah wait for results out @Sweety_Shah , they will give the final answer in the site. Hope fully they will change then , my marks would decrease by 5 then
