Answer:
<em>Scheme attached</em>
Explanation:
<em>Trans</em> effect is involved in this synthesis. As in the reactions of planer metal complexes, trans effect dominates the stereo-chemistry of the product.
<em>Trans</em> 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 <em>trans</em> effect it make the substitution difficult.
So when we attach NH₃ first to the ligand it make the trans substitution difficult, hence <em>cis</em> product will be formed.
As NO₂ has very low <em>trans</em> effect, so it doesn't effect the substitution and the <em>trans</em> product will be formed as usual.
Answer:
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results.
Explanation:
hope this is what you need
Subtract the group number from the atomic number.
