Question

 

Other than the X-ray diffractions, how could be the following pairs of isomers be distinguished from one another by  

[Cr(NH3)6][Cr(NO2)6] and [Cr(NH3)4](NO2)2]

[Cr(NH3)2(NO2)4]

Solution

Correct option is

Measurement of molar conductance

The former would conduct as a (3+ and 3–) electrolyte while the latter would conduct as (1+ and –1) electrolyte.
