Write down the reaction schemes including intermediate if any to show the preparation in aqueous solution for each of the stereo isomers of [pt (nh3)(no2)cl2]

Scheme attached

Explanation:

Trans effect is involved in this synthesis. As in the reactions of planer metal complexes, trans effect dominates the stereo-chemistry of the product.

Trans effect

The role of the element present in trans position to the element to be substituted is called the trans effect. The nature of the ligand in trans position effects the substitution, if it has high trans effect it make the substitution difficult.

So when we attach NH₃ first to the ligand it make the trans substitution difficult, hence cis product will be formed.

As NO₂ has very low trans effect, so it doesn't effect the substitution and the trans product will be formed as usual.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
