Arrange the following in decreasing order of their molar conductance in aqueous solution: (I) , (II) — Coordination Compounds Chemistry Question
Question
Arrange the following in decreasing order of their molar conductance in aqueous solution: (I) $K[Co(NO_2)_4(NH_3)_2]$, (II) $[Cr(ONO)_3(NH_3)_3]$, (III) $[Cr(NO_2)(NH_3)_5]_3[Co(NO_2)_6]_2$.
Answer: B
💡 Solution & Explanation
Conductance depends on the number of ions. (III) yields 5 ions ($3$ cations, $2$ anions). (I) yields 2 ions. (II) yields 0 ions (neutral). Order is III > I > II [5, 6].
