Create a detailed flow sheet for the following experiment. **Procedure for Separation and Analysis of Compounds**6) Add 15 mL of a saturated NaCl solution to a separatory funnel. Shake the funnel and allow the layers to separate. Draw off the lower layer. Carefully pour the ether layer into a 50 mL flask (referred to as flask 2). Add about 4g of anhydrous CaCl₂ and set it aside.7) Add NaOH dropwise into flask 1 until no more solid is produced. Cool the flask using an ice bath.8) Decant the ether layer from flask 2 into a new beaker, ensuring that all solid is left behind. Then, evaporate the solution.9) Collect the solid from flask 1 using suction filtration.10) Weigh the two compounds and test their melting points (m.p.).**Figure Explanation**- The diagram shows a separatory funnel with a Teflon stopcock. Below it is a stand supporting the funnel, which is being used to separate liquids based on their densities. The bottom layer can be drawn off by opening the stopcock, allowing for precise separation of the different phases. ## Extraction (Part 2)### Experiment: Separation of Neutral and Basic Substances#### Chemical Structures and Properties:- **Naphthalene**: Molecular structure with a melting point (mp) of 80°C.- **4-Chloroaniline**: Molecular structure with melting point (mp) 68-71°C and pKa 10.0.#### Safety Precautions:- **Warning**: Handle aromatic amines with care. Most are toxic and some are carcinogenic. Avoid breathing dust and vapors. Keep compounds off the skin, best managed by wearing gloves.#### Procedure:1. Dissolve 2g of the mixture in 20 mL of ethyl ether and transfer the mixture to a 125 mL separatory funnel.2. Add 10 mL of H₂O and 10 mL of a 3M HCl solution into the funnel.3. Stopper the funnel and shake the mixture thoroughly, frequently venting the funnel.4. Allow layers to separate completely. Draw off the lower layer into a 50 mL flask (flask 1).5. Repeat the process with another 10 mL of HCl. Draw off the lower layer into flask 1.#### Diagram:- **Figure 3**: Illustration of the correct position for holding a separatory funnel when shaking. This guides safe and effective mixing and separation of substances.This procedure outlines how to safely and efficiently separate neutral and basic substances for further analysis or experiments.

The above experiment is separation of basic and neutral compounds.

Extraction (Part 2) Experiment: Separation of Neutral and basic Substances NH2 Handle aromatic amines with care. Most are toxic and some are carcinogenic. Avoid breathing the dust and vapor from the solid and keep the compounds off the skin, best done by wearing gloves.

REACTION RECRYSTALLIZATION (OPTIONAL) 1. Begin assembling your reflux apparatus (i.e. lab jack, stir plate, exten- sion clamp and round-bottom flask of appropriate size). 10. Weigh your crude solid to calculate an approximate crude yield. Transfer most of it to a 125 mL erlenmeyer, but keep some aside (~100 mg) for analysis at the end. 2. Add para-aminophenol (15.0 mmol), demineralized water ([para- aminophenol] = 0.75 M) and a stirbar to the flask. Set to stir vigorously. 11. Recrystallize your solid by boiling in an erlenmeyer in a minimal volume of demineralized water (~8 mL/gram of crude solid) on a hot plate to fully dissolve it. If necessary, slowly add water portion-wise until a homogeneous solution is obtained. 3. Measure the required volume of acetic anhydride (1.30 eq.) in a small graduated cylinder. Using a platic pipette, add it to the reaction flask. 4. Finish the assembly of the reflux apparatus (i.e. secured water con- denser along with tubing, heating mantle and…

Practical and Efficient Synthesis of N-Formylbenzotriazole 1. ProcedureA 500-mL, 3-necked, round-bottomed flask (Note 1) equipped with a 5 cm Teflon-coated cylindrical magnetic stir bar, an internal thermometer, a rubber septum, and a Vigreux condenser capped with a rubber septum with an argon inlet, is charged with acetic anhydride (26.5 mL, 28.6 g, 280 mmol, 1.0 equiv) (Note 2). The contents are cooled to –10 °C by means of a Dewar filled with isopropanol and an immersion cooler (Neslab CC 100) (Note 3), then 100% formic acid (21.1 mL, 25.8 g, 560 mmol, 2.0 equiv) (Note 4) is added in portions to the flask over 3 min via a measuring cylinder [Caution: exotherm from –10 °C to 1 °C]. The resulting colorless reaction mixture is then heated in an oil bath on a hot plate to 43 °C (internal temperature) over 25 min. The reaction mixture is stirred vigorously for 3 h (42–44 °C, internal temperature) and monitored by 1H NMR analysis (Note 5).1H NMR analysis of crude reaction aliquots is…
