Question 7 What is the nucleophile in the following reaction Ferrocene + acetic anhydride + Phosphoric...
1. For the acetylation of ferrocene, ferrocene is mixed with acetic anhydride and 85% phosphoric acid and heated for 20 mins. Why is phosphoric acid used rather than a stronger acid such as sulfuric acid? 2. For the oxidation of ferrocene, NH4[PF6] is added to the reaction mixture of ferrocene, acetone, distilled water, and anhydrous FeCl3. What is the purpose of adding NH4[PF6]?
Question 16 What is the purpose of adding phosphoric acid in aspirin synthesis A) enhance the nucleophilicity of the OH of salicylic acid B) enhance the electrophilicty of acetic anhydride enhance the nucleophilicity of acetic anhydride D) enhance the electrophilicty of the carbonyl of salicylic acid А 8 С Question 17 Which statement(s) is correct for electrophilic aromatic substitution (EAS)? (multiple answer) ferrocene is more reactive than benzene A. benzene is more reactive than ferrocene B C. ferrocene is more...
How could the yield of diacetylated product be increased? (this reaction associated with Acetylation of ferrocene in present with acetic anhydride and phosphoric acid, diacetylaeted is minor product in the reaction)
Write the detailed balanced equation for synthesis of acetylferrocene from ferrocene and acetic anhydride. What is the function of the phosphoric acid in the reaction? Chemically, what role does thiamine plays in the catalysis of benzoin condensation? Name another catalyst that can also perform this reaction. Which catalyst for benzoin condensation is better? Why (3reasons)
In the mechanism for formation of acetylsalicylic acid via reaction of salicylic acid with acetic anhydride, phosphoric acid acts as a catalyst by O cleaving an acetyl group from acetic anhydride via protonation of the bridging oxygen O neutralizing the hydroxide ion side product protonating the carbonyl oxygen in the acetic anhydride protonating the phenolic oxygen of salicylic acid Question 10 (3 points) What would be the predicted major product from the thermodynamically controlled dehydration of the following material OH
QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...
