Co-Ordination Compounds Question 309
Question: $ {{[Fe,{{(en)}_2}{{(H_2O)}_2}]}^{2+}}+en\to $ complex (X). The correct statement about the complex (X) is -
Options:
A) it is a low spin complex
B) it is diamagnetic
C) it shows geometrical isomerism
D) [a] and [b] both
Show Answer
Answer:
Correct Answer: D
Solution:
Complex X is $ {{[Fe{{(en)}_3}]}^{2+}} $ ; as ’en’ is a strong field ligand pairing of electrons will take place.
Hence, hybridisation is $ d^{2}sp^{3} $ and complex is diamagnetic.
As it has 3 bidentate symmetrical ’en’ ligands so it will not show geometrical isomerism.
