Question
![**DDT Production Reaction**
DDT, an insecticide harmful to fish, birds, and humans, is produced by the following chemical reaction:
\[
2\text{C}_6\text{H}_5\text{Cl} + \text{C}_2\text{HOCl}_3 \rightarrow \text{C}_{14}\text{H}_9\text{Cl}_5 + \text{H}_2\text{O}
\]
*Reactants:* Chlorobenzene, Chloral
*Product:* DDT
**Laboratory Scenario**
In a government lab, 1184 g of chlorobenzene is reacted with 473 g of chloral.
**Questions**
a. What mass of DDT is formed, assuming a 100% yield?
Mass = [Answer] g
b. Which reactant is limiting? Which is in excess?
[Reactant] is limiting.
[Reactant] is in excess.
c. What mass of the excess reactant is left over?
Mass = [Answer] g in excess
d. If the actual yield of DDT is 246.0 g, what is the percent yield?
Percent yield = [Answer] %
**Explanation**: This exercise involves determining the limiting and excess reactants in a chemical reaction, calculating theoretical yield, and comparing it to actual yield to assess reaction efficiency.](https://content.bartleby.com/qna-images/question/1b897147-dac4-49d3-a0b7-87acbe9c344d/348403df-92b6-40e6-b1a1-c2c2f4be5e0e/fe0mj7g_processed.png)
