Draw the mechanism for the formation of the carbocation obtained. Explain why the solution of this carbocation is colored. See below for information on the experiment: To test for a carbocation in a lab, we did the following: 1) Dissolve a small amount of diphenylmethanol into methanol, and add concentrated sulfuric acid dropwise. This caused the solution to turn yellow/orange. 2) Dissolve a small amount of benzophenone into methanol, and add concentrated sulfuric acid dropwise. The solution remained clear.

Question:
In the second laboratory experiment (Day 2), the depolymerization of polyethylene terephthalate (PET) to the monomer terephthalic acid involves hydrolysis-type chemistry. A mechanism for this conversion is shown in Figure 8. The reaction employs potassium hydroxide, which undergoes nucleophilic addition to the PET polymer. The resulting tetrahedral intermediate can collapse with proton transfer to generate an alcohol byproduct and form a new carboxylic acid species. Under the basic reaction conditions, the resulting carboxylic acid undergoes deprotonation to give the...
