### 2.) How many ¹H-NMR and ¹³C-NMR resonance signals would you expect in each spectrum for 2-aminophenyl phenyl sulfide? #### Compound Structure: The structure of 2-aminophenyl phenyl sulfide is shown above. It consists of two phenyl rings connected by a sulfur atom. One of the phenyl rings has an amino group (-NH₂) attached to it at the ortho position. #### ¹H-NMR Spectrum: The graph displayed is a ¹H-NMR spectrum of 2-aminophenyl phenyl sulfide. The x-axis represents the chemical shift in parts per million (ppm), and the y-axis represents the signal intensity. - **Chemical Shifts and Assignments:** - **Peak A:** 7.447 ppm - **Peak B:** 7.22 ppm - **Peak C:** 7.21 ppm - **Peak D:** 7.10 ppm - **Peak E:** 7.09 ppm - **Peak F:** 6.77 ppm - **Peak G:** 6.75 ppm - **Peak J:** 3.27 ppm Peaks B and C have overlapped with the solvent peak, which has not been removed from this spectrum. #### Structural Diagram: The structural diagram below displays the 2-aminophenyl phenyl sulfide molecule with labelled hydrogen atoms corresponding to the peaks in the NMR spectrum. #### Analysis: In the context of ¹H-NMR, the various peaks correspond to different hydrogen environments in the molecule. The shifts provide insights into the hydrogen atoms' chemical environments within the molecule. --- This text serves to help students better understand the interpretation of ¹H-NMR spectra for specific organic compounds and how to correlate chemical shifts with molecular structure.
