Correct Option - 1
Detailed Solution:[Mn (CN)? ]³? → Mn³? i.e 3d? → t? g? , eg? (d²sp³), CN? is strong field ligand.
[Fe (CN)? ]³? → Fe³? i.e 3d? → t? g? , eg? (d²sp³), CN? is strong field ligand.
[Co (C? O? )? ]³? → Co³? i.e, 3d? → t? g? , eg? (d²sp³), C? O? ²? is strong field ligand.
[MnCl? ]? → Mn³? = 3d? → t? g²¹¹¹, eg¹¹? (4 unpaired e? ), Cl? is weak field ligand.
[FeF? ]³? → Fe³? = 3d? → t? g³¹¹, eg²¹¹ (5 unpaired e? ) F? is strong field ligand.
∴ S? and S? are true.
