WMK Mechanism Project You are expected to provide a mechanism from beginning to end with a detailed explanation of type of chemical reaction, mechanism, and labeling relevant reagent classes. Use the reaction steps to guide your mechanistic detail; note not all reagents, catalysts, and solvents are shown. For each mechanistic step, a. Label the Nucleophile/Base/Electrophile/Acid (if possible) b. Label each step according the mechanism: A. acid/base, B. bimolecular nucleophilic substitution, C. heterolysis, D. coordination, E. bimolecular elimination, F. electrophilic elimination,...

Draw a proposed mechanism for the reaction of cyclohexanol with aqueous sulfuric acid to yield cyclohexene. Label each step as either: nucleophilic attack, loss of a leaving group, or proton transfer. What type of elimination reaction is this: E1 or E2? Explain. Explain how the leveling effect has occurred in this reaction? What is the likely base in the last step: water or HSO4-? Explain.

Question 3 Consider the reaction shown below. CEN ОК KOH H20 Propose a detailed mechanism using curved arrows in a step by step manner to illustrate the formation of the carboxylic acid salt formed in this reaction. Make sure to use curved arrows to show the deprotonation, protonation, bonds formation or bonds cleavage.
Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism.
Acid-catalyzed dehydration of secondary and tertiary alcohols
proceeds through an E1 mechanism. The first step is the protonation
of the alcohol oxygen to form an oxonium ion. Dehydration of
3-methyl-2-butanol forms one major and two minor organic products.
Draw the structures, including hydrogen atoms, of the three organic
products of this reaction.
