Propose a structure for the polymer formed by intermolecular reaction of salicylic acid during the synthesis of aspirin. Which is the stronger acid, aspirin or salicylic acid?
Phenol group being close to carboxylate group in the salicylate anion, the phenol proton can form an intramolecular hydrogen bond to the carboxylate group. This stabilizes the anion, making the corresponding acid stronger. In aspirin it is not possible to form such a hydrogen bond. Therefore, the anion is less stable and the acid less strong.

In the lab calledd Synthesis of Aspirin, the mass of salicylic acid is 3.037g , the mass of dried Aspirin finally is 2.793. What is the moles of salicylic acid used? What is the moles of aspirin expected? What is the mass of aspirin expected?
Mass of salicylic acid recovered= 11.495g Used 1.410g of salicylic acid when synthesizing aspirin. Mass of acetylsalicylic acid(aspirin) recovered= 2.365g Discuss your yields, % yield of salicylic acid and aspirin. The reaction is the synthesis of salicylic acid from oil wintergreen, and then using the salicylic acid to synthesize aspirin. THANK YOU IN ADVANCE
When old aspirin breaks down salicylic acid is formed. What functional group does salicylic acid have that aspirin does not? -OH Opera Olaondo acid catalyst + some stuff -©—OH 0-C-CH3 + CH3—C—OH acetic acid OH aspirin Salicylic acid
Aspirin (acetylsalicylic acid) may be formed from salicylic acid and acetic acid as follows: 13a How many g of aspirin may be produced from 6.94 × 102 mol salicylic acid
Organic chemistry -Carboxylic acid homework Question: In the general chemistry lab, students synthesize aspirin from salicylic acid and acetic anhydride. In the lab, students use sulfuric acid as a catalyst, but I want to consider an alternate method for synthesizing aspirin using sodium acetate as a catalyst: a. Draw the structure of sodium acetate. Is sodium acetate a stronger or weaker base than sodium hydroxide (NaOH). Explain. (1.5 pts) b. Consider the structure of salicylic acid. It contains two potentially...
During the aspirin synthesis a student began with 4.057 grams of salicylic acid (density=1.443 g/mL, mol.wt. = 138. 12 g/mol) and 1.98 mL of acetic anhydride (d= 1.082 g/mL, Mwt= 102.09 g/mol). A total of 3.249 grams of aspirin was formed (m.wt 180.17 g/mol). What was the percent yield? 61.4 % 071.4% 80.1 % O 85.9 % Question 19 (3 points) In the oxidation of 9-Fluorenol to 9-Fluorenone, NaOCI serves as a: Nucleophile Drying agent Catalyst Reducing agent
