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

Options

A.measuring osmotic pressure of solution at same concentration
B.measurement of molar conductance
C.measuring magnetic moments
D.None of these

Solution

Sol. [Cr(NH3)]+3 [Cr(NO2)6]–3 and [Cr(NO2)2 (NH3)4]+1[Cr(NO2)4 (NH3)2]–1

have different molar conductance.
