Chemistry - Coordination Chemistry Question with Solution | TestHub
Werner isolated several octahedral complexes of cobalt(III) containing only and ligands. Five such compounds (labeled ) were obtained, while a sixth compound ( ) could not be isolated by him but is the isomer of . Their molar conductivities (extrapolated to infinite dilution) are given below :
Additional observation : • X does not react with aqueous AgNO3
• X1 , X2 , X3 give different stoichiometric precipitates with aqueous AgNO3 in the same stoichiometric ratio. Which of the following statements is INCORRECT?
Options:
Answer:
Solution:
- Co(III) is low-spin , hence all complexes are diamagnetic and colored.
- Conductivity values correspond to ionization isomers of . - X₅ has no ionizable chloride (all within coordination sphere). - X₃ and X₄ have the same conductivity but different stereochemistry.
