## Question 2 ### a. Considering the five compounds shown below, which one matches the given \( ^1H \) NMR spectrum? Circle your answer. **Compounds:** - **A:** ![Compound A](image_of_compound_A) - **B:** ![Compound B](image_of_compound_B) - **C:** ![Compound C](image_of_compound_C) - **D:** ![Compound D](image_of_compound_D) - **E:** ![Compound E](image_of_compound_E) **NMR Spectrum Explanation:** The provided \( ^1H \) NMR spectrum includes: - A signal at approximately 3.8 ppm integrating to 2H. - A signal at approximately 1.2 ppm integrating to 6H. - A signal at approximately 1.1 ppm integrating to 3H. - A signal at approximately 2.2 ppm integrating to 1H. ### b. Clearly match each peak in the NMR spectrum to a specific set of H atoms in your chosen structure. Use Ha, Hb, etc. for your labels on both your structure and spectrum. In compound E, the peaks can be assigned as follows: - The peak at 3.8 ppm (2H) corresponds to Ha. - The peak at 1.2 ppm (6H) corresponds to Hb. - The peak at 1.1 ppm (3H) corresponds to Hc. - The peak at 2.2 ppm (1H) corresponds to Hd. ### c. List all of the compounds (A, B, C, D, E) that you would expect to have an IR peak at 1710 cm^-1. If none, write “NONE”. The compounds expected to have a peak at 1710 cm^-1 are those containing a carbonyl group (C=O): - **B** - **C** - **E** ### d. List all of the compounds (A, B, C, D, E) that you would expect to have an IR peak at 3300 cm^-1. If none, write “NONE”. The IR peak at 3300 cm^-1 indicates an O-H (assuming alcohol or phenol) or N-H bond: - **NONE** ### e. List all of the compounds (A, B, C, D, E) that you would expect to have an
