CHEM 2364 Final Alfonso Exam Questions with Correct Answers Latest Update 2025/2026

CHEM 2364 Final Alfonso Exam Questions with Correct Answers Latest Update 2025/2026 In a certain scenario, you have a separatory funnel containing two unknown colorless, clear, and immiscible layers. How would you determine which is is the organic layer and which is the aqueous layer? Read the options carefully below. Select the answer that accomplishes this. - Answers Remove a small amount of the bottom layer, and add a few drops of water to see if it is miscible. Which of the following statements are correct regarding the use of a separatory funnel? - Answers Venting a separatory funnel is important in part because the acid-base reactions can generate gas products, which creates an explosion hazard. Match the purpose of each reagent to the reagent in the separation for Exp. 4. Wash the organic layer - Answers NaCl (brine) Match the purpose of each reagent to the reagent in the separation for Exp. 4. Remove water from the organic layer - Answers MgSO4 Match the purpose of each reagent to the reagent in the separation for Exp. 4. Extract acetaminophen into the aqueous layer - Answers KOH Which answer choice correctly explains partitioning (seen in Exps. 3, 4, and 5)? - Answers When a molecule travels to the layer (or phase) that it is most attracted to due to similar intermolecular forces. Which reagent(s) can be used to deprotonate acetaminophen in Exp. 5? Select all that are correct. - Answers KOH Match the purpose of each reagent to the reagent in the separation for Exp. 5. Protonate aspirin or acetaminophen - Answers HCl Match the purpose of each reagent to the reagent in the separation for Exp. 5. Extract aspirin into the aqueous layer - Answers K2HPO4 Match the purpose of each reagent to the reagent in the separation for Exp. 5. Organic layer solvent - Answers ethyl acetate EXP 5 acetysalicylic acid, acetaminophen, caffeine - K2HPO4 - what goes in the 1st organic layer - Answers caffeine (C) EXP 5 acetysalicylic acid, acetaminophen, caffeine - K2HPO4 - what goes in the 1st aq layer - Answers acetylsalicylate [ AA(ion) ] EXP 5 acetysalicylic acid, acetaminophen, caffeine - KOH - what goes in the 2nd organic layer - Answers caffeine EXP 5 acetysalicylic acid, acetaminophen, caffeine - KOH - what goes in the 2nd aq layer - Answers acetmainophenoxide [ A(ion) ] Experiment 6 Select the answer that correctly explains the setup for the water flow in the condenser: - Answers The water flows in at the bottom barb and out at the top, since the water is coldest when coming from the tap and will heat up as it runs through the condenser. Experiment 6 Given the following two reagents, which is likely the product if they undergo a Diels-Alder reaction - Answers LOOK AT PIC In a microscale version of Exp. 6, 0.281 g anthracene (C14H10) and 0.194 g of maleic anhydride (C4H2O3) are reacted as shown: Determine the theoretical yield of the limiting reagent in grams. Make sure your answer has the correct units and the correct number of significant figures. - Answers 0.281 g C14H10 x 1 mol C14H10 x 1 mol C4H2O3 x 276.3 g 178.23 g C14H10 1 mol C14H10 1 mol C4H2O3 = 0.436 g Experiment 6 Below is a developed TLC plate for a student who was analyzing their Diels-Alder reaction and product. Which answer choice is likely true about the results of this reaction? Notes: The "S" lane was the reactant anthracene. The "M" lane was a mixture of what was in the "S" lane and the "P" lane. The "P" lane was theoretically the product (what is present after the reaction is assumed to be over). All three dots are even. - Answers The reaction did not take place at all since both the mixture and the product lane only has one spot with the same Rf. Experiment 6 Given the following IR spectrum and the Table of Functional Groups, identify the bond associated with each band between cm-1, then identify the probable functional group.
