Question

1. Draw the reaction mechanism for the formation of Grignard product

From : Benzaldehyde to  Diphenylmethanol

2.Calculate the theoretical yield for the reaction. Show your calculations.

3. Calculate the % yield of the reaction and the % error of the melting point. Show the calculations.

4. Locate an IR spectrum for the product in the literature

5. NMR analysis:

• Draw the full structure of the product. Show all bonds to the hydrogens. Label the different sets of hydrogens (i.e. H_a. H_b, H₁, H₂, etc) based on which ones are equivalent and which ones are not.
• Assign each set of hydrogens with a specific signal on the spectrum.
• Create a table that summarizes: the chemical shift, integration, multiplicity, proton assignment, and justification of each signal.

Please answer as many as you can. Really would appreciate the help! Thank you!
