- Shown below is a two-step mechanism beginning with nucleophilic attack of water, and subsequent deprotonation with a base. Draw the arrows for the mechanism for both step 1 and step 2 and draw the intermediate product of in the box. + H-O OH + H₂Oarrow_forwardWhen the following deuterium-labeled compound is treated with potassium tert-butoxide in DMF, a single product is observed. When the same substrate is heated in the presence of dilute potassium ethoxide in ethanol, a mixture of two products is formed. Provide the complete, detailed mechanism (curved arrows) for each reaction and label each reaction as E1 or E2. Note: deuterium is an isotope of hydrogen and can be treated similarly to hydrogen in chemical reactions but cannot be implied.
