4. a) Identify the difference(s) in structure of adipic acid (CAS 124-04-9) and Malonic Acid (CAS 141-82-2). b) Explain how this difference(s) in structure accounts for the solubility of the two compounds in water. Focus on polarity and intermolecular forces of the molecules and the solvent. c) Explain why the compound vanillin (CAS 121-33-5) demonstrates different solubility in ethyl acetate and hexane. Focus on the structure and the intermolecular forces of the solute and solvent.

I. Nylon 6-6 is a condensation polymer. The last two lab handouts pointed out that "condensation reactions are extremely common among a variety of organic functional groups." Pick two appropriate functional groups (your choice) and draw structures to show the condensation reaction between them. Identify the functional groups that are reacting, as well as the linkage formed by the condensation. 2. Rather than use a carboxylic acid for the nylon condensation, you'll use the more reactive acid chloride. This must...

Re-draw the chemical structure of cinnamaldehyde (from the Reaction Scheme) and use it to answer the following solubility-based questions: 1. Circle and label all regions of the molecule that exhibit non-polar behavior. 2. Circle and label the region of the molecule that exhibits polar behavior. 3. Water prefers to interact with solute molecules with what type of intermolecular force (choose one answer): hydrogen bonding, dipole-induced dipole, or induced dipole-induced dipole (London dispersion)? 4. Based on the answers to parts (a)-(c),...

answers.
Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...
