JEE Advanced Chemistry question

and will differ in (I = Colour, II = Structure, III = Hybridisation)

(A)I,III
(B)II,III
(C)I,IICorrect
(D)I,II,III

Answer: (C)

Solution

As linkage isomers, these two complexes differ in which atom of is bonded to the metal — this changes the colour (I) of the complex and also constitutes a difference in structure/connectivity (II, the bond is Co–N in one
