Which one of the following has the highest molar conductivity?

Options

  1. ADiammine dichloroplatinum (II)
  2. BTetraamminedichlorocobalt (III) chloride
  3. CPotasșium hexacyano ferrate (II)
  4. DHexa aquo chromium (III) chloride

Correct answer

C. Potasșium hexacyano ferrate (II)

Step-by-step solution

Highest molar conductivity (for equimolar solutions) will be exhibited by the complex that will dissociate into a greater number of ions in the solution. aligned & [ Pt ( NH ₃ )₂ Cl ₂ ]=0 & [ Co ( NH ₃ )₄ Cl ₂ ] Cl =2 & ~K ₄ [ Fe ( CN )₆ ]=5 & [ Cr ( H ₂ O )₆ ] Cl ₃=4 aligned Thus, potassium hexacyano ferrate (II) will have the highest molar conductivity.
