Show how to convert ethylene to 2-Chloroethanol compound.

Because phenol (C6H5OH) is less acidic than a carboxylic acid, it can be deprotonated by NaOH but not by the weaker base NaHCO3. Using this information, write out an extraction sequence that can be used to separate C6H5OH, benzoic acid, and cyclohexanol. Show what compound is present in each layer at each stage of the process, and if it is present in its neutral or ionic form.

Starting with cyclohexanone and ethanol as the only organic reagents, use any inorganic reagents to propose a synthesis for the target molecule.

How can you use TLC to determine if a chemical reaction has gone to completion? For example, treatment of cyclohexanol in the presence of a non-nucleoplhilc acid, sulfuric acid gives the corresponding alkene, cyclohexene via an E1 reaction.   Draw 3 examples of TLC plates: a) at the beginning of the reaction, b) during the reaction, and c) at the completion of the reaction. Explain what is shown on each plate. Hint: What are the dominant intermolecular interactions of cyclohexanol and cyclohexene?
