Pre-Laboratory Assignment • What particular precautions should you take 3. Methyl alcohol, CH,OH, reacts with benzoic acic when doing the following: CHECO,H, to form an ester. (1) using concentrated sulfuric acid (1) Using structural formulas, write the equatic for this reaction. (2) using glacial acetic acid (3) using a warm-water bath (2) What is the name of this ester? (4) Smelling ester odors 2. What is the purpose of the concentrated sulfuric acid used in this experiment?

H3PO4 OH + OH OH salicylic acid acetic anhydride acetic acid acetylsalicylic acid (aspirin) 1. Why is it better to perform acetylation with acetic anhydride rather than using a Fischer esterification with acetic acid? 2. Draw a complete arrow-pushing mechanism for the reaction. 3. When an old sample of aspirin is left in moist conditions, it will begin to smell like vinegar. Draw a reaction scheme and briefly explain what happened.

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...

2. If one were esterifying an expensive alcohol with an expensive carboxylic acid derivative, would it be wiser to use the acid chloride or acid anhydride reagent? Why? 3. Why is so much NaOH used in the extraction? Recall that only four drops (small amount) of sulfuric acid were used as a catalyst. Esters are an important class of organic molecules, which are formally derived from alcohols and carboxylic acids. Esters occur widely in nature and are often an important...

1. Answer with octyl ethanoate as the esterfication reaction (alcohol: 1-octanol, 3.25ml and carboxylic acid: ethanoic acid, 1.25ml) (a) Write a complete chemical equation for the esterfication reaction, use structural formulas and write the name of each compound under the formula. (b) define if the esther is polar or non-polar (c) determine the molar ratio of the two reactants, alcohol and carboxylic acid using the balanced chemical reaction (d) calculate the molar mass of the alcohol and carboxylic acid (e)...
