isomers of [Pt (nh3)(no2)Cl2]
1 answer:
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.

This is an exercise in<u> the General Combined Gas Law</u>.
To start solving this exercise, we obtain the following data:
<h3>Data:</h3>- V₁ = 4.00 l
- P₁ = 365 mmHg
- T₁ = 20 °C + 273 = 293 K
- V₂ = 2,80 l
- T₂ = 30 °C + 273 = 303 K
- P₂ = ¿?
We apply the following formula:
- P₁V₁T₂=P₂V₂T₁ ⇒ General formula
Where:
- P₁=Initial pressure
- V₁=Initial volume
- T₂=end temperature
- P₂=end pressure
- T₂=end temperature
- V₁=Initial temperature
We clear for final pressure (P2)
We substitute our data into the formula:
Answer: The new canister pressure is 539.224 mmHg.
