In this experiment we consider the hydrolysis of dilute acetic anhydride in water where we will replace light water (H2O) with heavy water (D2O) and compare the reaction kinetics. Match the functional groups and classes of organic compound to their name. ²₂+40-2 + H02 CH3COH CH 3 OH C=O COOH RCOOH RCOOR ester carboxyl carbonyl carboxylic acid hydroxyl

To determine the purity of a synthetic preparation of methylethyl ketone, C4H8O, it was reacted with hydroxylamine hydrochloride, liberating HCl (reaction: NH2OH.HCl + C4H8O -> C4H9NO + H20 + HCl). In a typical analysis a 3.00-mL sample was diluted to 50.00 mL and treated with an excess of hydroxylamine hydrochloride. The liberated HCl was titrated with 1.2149 M NaOH, requiring 35 mL to reach the end point. A. Write the acid base reaction involved in the titration. B. Report the percent purity of the sample given that the density of methylethyl ketone is 0.805 g/mL.

17) After the reaction, Gwen sees a solid appear. She should collect this solid by rotary evaporator vacuum filtration TLC gravity filtration 18) After completing the separation and purification, Gwen checks the purity of her isolated mandelic acid on a polarimeter. She takes 0.525 g of solid and dissolves it in 5 mL of acetone. She puts this in a tube with a pathlength of 1 dm. The polarimeter gives a reading of +13.0011 deg.

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?
6) During the Wittig reaction, you perform the reaction as follows:4-chlorobenzaldehyde (136 mg) and (carbethoxymethylene)triphenylphosphorane(323 mg) were placed in a 25 mL Erlenmeyer flask. The two solids were mixed vigorously for 15 min. The reaction mixture was diluted with hexanes (2.9 mL - density 0.661 g/mL) The by-product, triphenylphosphine oxide, was filtered off.0.085 g total of triphenyl phosphine was isolated. The filtrate was then evaporated to dryness to obtain 0.151 g of the desired product, pure ethyl-4-chlorocinnamate, as a colorless oil.What is the % effective mass yield of the reaction? (Your result should be reported as a % value and rounded to the nearest integer.
TLC, a powerful analytical tool, can be used to monitor the progress of reactions. The synthesis of ethyl-3-coumarincarboxylate can be monitored by TLC by displaying the starting aldehyde 1, and coumarin product 2, which have very distinct Rf values (Hint: Think about the polarity of compounds 1 and 2 in terms of their abilities to H-bonds to silica gel). What can be determine about the progress of the reaction from analysis of the TLC shown below?
