JEE Main 2019 Chemistry question
The correct statements among I to III are: (I) Valence bond theory cannot explain the color exhibited by transition metal complexes. (II) Valence bond theory can predict quantitatively the magnetic properties of transition metal complexes. (III) Valence bond theory cannot distinguish ligands as weak and strong field ones.
Answer: (D)
Solution
VBT gives no quantitative magnetic data and cannot explain colour or ligand field strength.
