Arrange the following in order of increasing molar conductivityMg[Cr(NH3)(Cl)5][Cr(NH3)5Cl]3 [COF6]2[Cr(NH3)3Cl3]

To arrange the given compounds in order of increasing molar conductivity, we need to consider the number of ions they will produce when dissolved in a solution. Molar conductivity depends on the number of ions produced per mole of a compound. The more ions a compound produces, the higher its molar conductivity.

1. [COF6]2: This compound will dissociate into 3 ions in solution (1 Co2+ ion and 6 F- ions).

2. [Cr(NH3)3Cl3]: This compound will dissociate into 4 ions in solution (1 Cr3+ ion and 3 Cl- ions).

3. Mg[Cr(NH3)(Cl)5]: This compound will dissociate into 7 ions in solution (1 Mg2+ ion, 1 Cr3+ ion, 5 Cl- ions and 1 NH3 molecule which does not contribute to conductivity).

4. [Cr(NH3)5Cl]3: This compound will dissociate into 9 ions in solution (3 Cr3+ ions, 3 Cl- ions and 15 NH3 molecules which do not contribute to conductivity).

So, the order of increasing molar conductivity is: [COF6]2 < [Cr(NH3)3Cl3] < Mg[Cr(NH3)(Cl)5] < [Cr(NH3)5Cl]3.
