4. TLC Data: Provide a drawing of your TLC plate with proper labels, and specify which solvent system was used to develop the TLC. Comment on the purity of your product according to TLC. Explain why the newly produced phenacetin would run higher on the TLC plate compared to the starting material acetaminophen.

Alcohols and Ethers 185 14.3 THE WILLIAMSON ETHER SYNTHESIS: PREPARATION OF PHENACETIN FROM ACETAMINOPHEN One of the most common methods used to prepare ether Williamson ether synthesis. In this reaction, an alkoxide anion (RO) acts as a nucleophile in an S, 2 process, displacing a leaving group (X) from an electrophile (R-X). R-20 . RY ROR...

Organic chemistry post-lab question: "Why is important
to add the alkyl halide dropwise in your reaction? (Hint: your
reaction is not heated, but you still need a water-cooled
condenser!)" Please answer in detail!

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
Implementation of Activity-Based Costing (ABC) The case of a Juice Company
John Orland, controller of the Juice Company, has been concerned over the erosion of the recent financial results especially for the standard flavors (A and B) which used to earn a hefty 20 per cent of profit margin. Recently, Dan Brun, the sales manager has expanded the lines of products to encompass new flavors (B & C) which were in high demand by customers who were willing to pay 5 to 10 % premium. Richard Dunn, the manufacturing...
