![### Determining the % Atom Economy
The % atom economy is an important concept in green chemistry. It measures the efficiency of a chemical reaction in terms of how well atoms are utilized in the desired product. Higher atom economy means a more efficient and environmentally friendly process.
**Problem:**
Determine the % atom economy for the production of 1-bromobutane from 1-butanol. Assume it is a one-step reaction, given by the following chemical equation:
\[ \text{H}_3\text{C-CH}_2\text{-CH}_2\text{-CH}_2\text{-OH} + \text{NaBr} + \text{H}_2\text{SO}_4 \rightarrow \text{H}_3\text{C-CH}_2\text{-CH}_2\text{-CH}_2\text{-Br} + \text{NaHSO}_4 + \text{H}_2\text{O} \]
**Answer:**
Enter your answer in the space provided below:
\[ \boxed{ \quad \quad \quad } \]
### Steps to Solve:
1. **Identify the desired product**: In this reaction, the desired product is 1-bromobutane (H₃C-CH₂-CH₂-CH₂-Br).
2. **Calculate the molar masses** of all reactants and products.
3. **Determine the total mass of reactants**: Sum the molar masses of H₃C-CH₂-CH₂-CH₂-OH, NaBr, and H₂SO₄.
4. **Calculate the mass of the desired product**: The molar mass of 1-bromobutane (H₃C-CH₂-CH₂-CH₂-Br).
5. **Use the formula for % Atom Economy**:
\[
\% \text{Atom Economy} = \left( \frac{\text{Molar Mass of Desired Product}}{\text{Total Molar Mass of Reactants}} \right) \times 100
\]
By applying these steps, students can determine the % atom economy for the given reaction, fostering a greater understanding of the principles of green chemistry.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0e989a36-a976-4f9a-8f93-2801096d9bdd%2Febe794d0-9d6d-4129-a1d3-2fe7c8ff7b47%2F5rdsbzj_processed.png&w=3840&q=75)
