Q. Which one of the following has the highest molar conductivity?
A) Diaminedichloroplatinum (III)
B) Tetraaminedichlorocobalt (III) chloride
C) Potassium hexacyanoferrate (II)
D) Hexaaquochromium (III) bromide
Explanation
(c)
The molar conductivity of potassium hexacyanoferrate (II)
$i.e.,\ K_{4}\lbrack Fe\left( CN)_{6} \right\rbrack$ is highest because it gives maximum number of ions on ionization.
$K_{4}\lbrack Fe\left( CN)_{6} \right\rbrack \longrightarrow \ {4K}^{+} + \ \lbrack Fe(CN)_{6}\rbrack^{4 -}$
