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?

The glycerol carbonylation reaction with CO₂ to produce glycerol carbonate (Figure 1) is thermodynamically hindered due to several reasons including the presence of water as a by-product and the stability of CO2 as a co-reactant. Discuss the possible approach to overcome the issues and be able to produce a higher yield of targeted glycerol carbonate. 0 OH 0 Cat. A HO LOH + CO₂ + H₂O HO. Figure 1

Create a flow chart of the separation of an alkane by a clathrate (using hexadecane and 2,2,4-trimethylpentane, urea, methanol, and anhydrous calcium chloride)

You were asked to separate compounds A, B, and C extracted from a plant material through steam distillation. In your experiment, you were able to collect three distillates at different temperatures. In order to classify the compounds in each distillate, you performed several physical and chemical tests. The results are tabulated below. Based on the Results, what are the identities of the terpenoids in each distillate?

Calculate The Theoretical Yield Of Alkenes For the acid catalyzed dehydration of 2-methyl-2-butanol Note: 20.0 ml of 2-methyl-2-butanol were used and 10 mL of concentrated sulfuric acid  were used. Note the real amount produced was 10.92 g.

The alkene shown below is treated sequentially with ozone (03) and zinc/acetic acid. Draw structural formula(s) for the organic product(s) formed. CH3 CH3CHCHCH=CH₂ CH3 0 • You do not have to consider stereochemistry. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple products using the + sign from the drop-down menu. ● ▾ 90-85 ChemDoodle - [] la

Can someone please help me out with this? It has to have Hyaluronic Acid, (C14H21NO11)n, as either the product or the starting material. Thanks in advance!

Chemistry: 1) SAM reacts with nucleophiles in an SN2-like reaction in our body for a variety of important biosynthetic reactions.
