- Classify following solvent as protic or aprotic CH3NO2[Grignard Synthesis of Benzoic Acid] Characterization 1. Explain melting point determination as a characterization technique 2. Explain IR spectroscopy as a characterisation technique.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…

- What is the purpose of combining nitric acid with sulfuric acid before starting a nitration reaction on an aromatic substrate? Sulfuric acid is necessary to react with nitric acid and form NO2+. Sulfuric acid is a necessary solvent. All aromatic compounds are soluble in sulfuric acid, but insoluble in nitric acid. Sulfuric acid plays no significant role. We are just following the procedure, which calls for sulfuric acid, even though it has no effect. Sulfuric acid is necessary to dilute the nitric acid. Concentrated nitric acid alone reacts too quickly and risks nitrating the substrate a second or third time.If the structure below is subjected to retrosynthetic analysis, which reagent is least useful?Apply retrosynthetic analysis to identify all the practical combinations of Grignard reagent and aldehyde or ketone that will give the required target.
- 1. Why was extraction by both acid AND base necessary to arrive at highly purified benzoic acid?could someone please show me the mechanis m for this reaction, thank you i will appreciate it !!Write TRUE if the statement is correct and FALSE if the statement is wrong. Please answer them all Substitution reactions do not occur in aromatic rings because of pi-electron delocalization. The resulting iodinated aspirin has a higher Rf compared to aspirin after visualizing with ferric chloride. The mobile phase used in determining the Rf of the iodinated aspirin is 5% ethyl acetate in acetic acid. When isopropyl alcohol reacts with HCI, the resulting product is 2-chloropropane. In Fehling's test, the theoretical product after an aldehyde is mixed with Fehling's Solution is alcohol. lodoform, which has a molecular formula of CH3l, is indicative that a ketomethyl group is present. Based on the physical property, hydroquinone has a lower boiling point compared to catechol. Picric acid, being a phenolic compound, tests positive for the FeCl3 test. Nucleophilic molecules are electron-rich molecules that can "attack" electron-deficient molecules. When FeCl3 is used in visualizing…
