Describe the 1H-NMR spectrum of p-bromoacetanilide (chemical shift, integration, multiplet). Discuss in 2-3 sentences typed.
![**4'-Bromoacetanilide (103-88-8) \(^{1}\text{H}\) NMR Analysis**
**Product Basic Information:**
- **Product Name:** 4'-Bromoacetanilide
- **CAS:** 103-88-8
**NMR Experimental Conditions:**
- **Frequency:** 89.56 MHz
- **Sample Preparation:** 0.048 g in 0.5 ml DMSO-d₆
**NMR Spectrum Overview:**
- The spectrum displays the chemical shifts in ppm along the x-axis, with intensity on the y-axis.
- Key peaks are observed, indicating different hydrogen environments in the molecule.
**Molecular Diagram:**
- The molecule features a benzene ring substituted with a bromo group and an acetamido group.
- The hydrogen atoms are labeled \( \text{H}^{\text{A}}, \text{H}^{\text{B}}, \text{H}^{\text{C}}, \text{H}^{\text{D}} \).
**Peak Assignments:**
- **\( \text{H}^{\text{A}} \):** 10.03 ppm
- **\( \text{H}^{\text{B}} \):** 7.54 ppm
- **\( \text{H}^{\text{C}} \):** 7.48 ppm
- **\( \text{H}^{\text{D}} \):** 2.053 ppm
**Detailed Peak Positions and Intensities:**
- 898.31 Hz (10.031 ppm), Intensity: 39
- 684.06 Hz (7.639 ppm), Intensity: 42
- 683.75 Hz (7.635 ppm), Intensity: 48
- 683.19 Hz (7.629 ppm), Intensity: 38
- 680.94 Hz (7.604 ppm), Intensity: 29
- 677.31 Hz (7.563 ppm), Intensity: 471
- 674.56 Hz (7.532 ppm), Intensity: 376
- 673.00 Hz (7.515 ppm), Intensity: 113
- 672.50 Hz (7.509 ppm), Intensity: 109
- 670.94 Hz (7.492 ppm), Intensity:](https://content.bartleby.com/qna-images/question/e95435bc-a475-4a00-877d-f3d82e369349/375940a5-b03c-4046-836f-5c5082737627/f401qks_thumbnail.png)
