Question
**Question 9: Using the provided chart, predict the \( ^1H \) NMR spectrum of phenacetin.**

The image includes a chemical structure of phenacetin with labeled hydrogen atoms, and a table for predicting the \( ^1H \) NMR spectrum.

**Chemical Structure:**
- The chemical structure of phenacetin shows various hydrogen atoms labeled as \( a, b, c, d, e, \) and \( f \).

**Table for Predictions:**
- **Assignment:** Labels for each hydrogen as \( a, b, c, d, e, f \).
- **Expected ppm:** Space for entering expected chemical shift values in parts per million (ppm) relevant to each hydrogen label.
- **Expected integration:** Space for entering the expected integration, corresponding to the number of hydrogens causing the peak.
- **Expected multiplicity:** Space for stating the expected multiplicity of each signal, indicating the splitting pattern.

This setup is used for students to fill in the details on predicted chemical shifts, integrals, and multiplicities of protons in phenacetin using \( ^1H \) NMR data.
