Which of the following has highest molar conductivityA. Diamminedichlo

1.	Which of the following has highest molar conductivityA. Diamminedichloroplatinum (II)B. Tetraaminedichlorocobalt (III) chlorideC. Potassium hexacyanoferrate (II)D. Hexaaquochromium (III) bromide
Answer» Correct Answer - C As the number of ionsif complex compounds when dissolved in water increases, molar conductivity also increases. 1 mole of `[Pt(NH_(3))_(2)Cl_(2)]` gives one mole of ions. 1 mole of `[Co(NH_(3))_(4)Cl_(2)]Cl` gives two mole of ions 1 mole of `K_(4)[Fe(CN)_(6)]` gives five moles of ions 1mole of `[Fe(CO)_(5)]` gives zero moles of ions `[` because it is a neutral molecule ] Hence, `K_(4)[Fe(CN)_(6)]` has the highest molar conductivity
