Post Lab Questions – Grignard (You may write the answers only in your notebook for the post lab questions if you choose.) 1. In the synthesis of triphenylmethanol, benzene is often detected as an impurity. Explain, using structures, how the benzene is produced. 2. Propose the structure of the byproduct you can expect to form if acetone contaminated the container you used to prepare the benzophenone for this experiment? 3. During the recrystallization of triphenylmethanol, if excess ethanol is removed by boiling the solvent, and residual acid remains, a product has been shown to form that was identified as 1-ethoxy-1,1,1-triphenylmethane.

Unformatted text preview: Propose a mechanism that explains this result. 4. The spectra below highlight how hydrogen bonding can affect the position and the appearance of the IR absorption band for a hydroxyl functional group. A.) How does hydrogen bonding apparently influence the broadness of the absorption for a hydroxyl functional group? B.) Also, how does hydrogen bonding influence the relative position or wavenumber of both absorption bands? Use the following equation derived from Hooke’s law in your explanations: λ = the wavelength of light, k = a constant, f = bond strength, m = mass of atoms....
