**Question 3:**Using tables 22.3, 22.4, and 22.5, predict the shift for the protons attached to the atom indicated by the arrow. Report your answer in ppm to the tenths' place. Don't include the units in the answer.[Diagram of a molecular structure]- The diagram shows a benzene ring attached to a carbon chain. The chain has a double bond at the second position. - An arrow indicates a specific hydrogen (proton) positioned on the single-bonded carbon adjacent to the benzene ring and double bond (allylic to both structures).**Note:** Use the referenced tables to determine chemical shift values based on the molecular environment of the highlighted hydrogen. **Table 22.3: Additive Parameters for Predicting NMR Chemical Shifts of Alkyl Protons in CDCl₃****Base Values:**- Methyl: 0.9 ppm- Methylene: 1.2 ppm- Methine: 1.5 ppm---**Substitution Groups (Y) and Their Parameters:**| Group (Y) | Alpha (α) Substituent | Beta (β) Substituent | Gamma (γ) Substituent ||----------------------|-----------------------|----------------------|-----------------------|| —R | 0.0 | 0.0 | 0.0 || —C≡C | 0.8 | 0.2 | 0.1 || —C≡C—Arᵇ | 0.9 | 0.1 | 0.1 || —C≡C(C=O)OR | 1.0 | 0.3 | 0.1 || —C≡C—R | 0.9 | 0.3 | 0.1 || —C≡C—Ar | 1.2 | 0.3 | 0.2 || —Ar | 1.4 | 0.4 | 0.1 || —C(=O)OH | 1.1 | 0.3 | 0.1 || —C(=O)OR | 1.1 | 0.3 | 0.1 || —C(=O)H | 1.1 | 0.4 | 0.1 || —C(=O)R | 1.2 | 0.3 | 0.0 || —C(=O)Ar | 1.7 | 0.3 | 0.1 || —C(=O)NH₂ | 1.0 | 0.4 | 0.1 || —C(=O)Cl | 1.8 | 0.4

1. Using the values from the helium emission spectrum, generate a calibration curve on Microsoft Excel or other graphing software. If you are new to Microsoft Excel, specific instructions (with pictures) are given at the end of this lab and will be discussed in lab. a) In Excel, create a column labeled "scale position." This will serve as your x-values. Create another column labeled "wavelength." This will serve as your y-values. b) Enter the values for your scale position and wavelengths into each column. Do not put unit labels with the numbers. c) Create four separate graphs, one each for the four required types of trendlines ("linear", "logarithmic", "exponential", and "polynomial"). Each graph will have the same data plotted but have a different trendline. See the "Curve Fitting Using an Excel Spreadsheet" section at the end of this write-up for additional information about how to make these graphs. i.
