8. 1 pt] 4-chlorobenzaldehyde and 4-bromoacetophenone are both solid starting materials for the synthesis of substituted chalcone. When both of these compounds are ground with solid sodium hydroxide, the entire reaction mixture turns liquid. Explain why the solid reactants turn liquid when intimately mixing them. (Hint: What are the final products of the reaction?)

The Chalcone starting materials are:
p-bromoscetophenone (solid)
p-chlorobenzaldehyde (solid)
6. [1pt] When you treated the reaction TLC with 2,4-dinitrophenylhydrazine solution, you must have observed that the starting materials show up as bright orange spots instantaneously, whereas the product either shows no change or appears as a faint spot. Explain this observation. 8. [1 pt] 4-chlorobenzaldehyde and 4-bromoacetophenone are both solid starting materials for the synthesis of substituted chalcone. When both of...

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...

4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...

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...
