Solution
The correct option is A2 Reactant [M(NH3)2(py)2(NO2)2] is of type [Ma2b2c2] and product [M(NH3)3(py)2(NO2)] is of type [Ma3b2c].
We know [Ma2b2c2] type of complexes show 5 geometrical isomers.
And complexes of type [Ma3b2c] show 3 geometrical isomers.
Hence, difference between possible geometrical isomers of reactant and product is 5−3=2.
