acetylsalicylic acid vs salicylic acid? What is the main chemical difference? Why can acetylsalicylic acid pass through the stomach without harm while salicylic acid can cause harm to the stomach????

Ester compounds often have a sweet, pleasant odor. Many characteristic fruit scents are largely due to the natural presence of one or more ester compounds. As such, artificial scents for foods are often composed of complex mixtures of various esters. The exact identity and ratio of ingredients that compose a particular scent are closely guarded secrets in the food and fragrance industry. Suppose that you are a chemist working for a company that i creating a new line of air fresheners. The company is considering three scents: apple, pear, and pineapple. The project manager has asked you to prepare the ester compounds that are largely responsible for these scents. The structural formulas for these ester compounds are shown here: Alcohols for Air Freshener Project Molar mass Density Cost, per (g/mL) Reagent (g/mol) 1.00 L methanol 32.04 0.79 $46.20 ethanol 46.07 0.79 $112.00 1-propanol 60.10 0.80 $72.70 1-butanol 74.12 0.81 $72.60 Use the structural formulas of the alcohols and…

The following figure shows a typical phospholipid. Suppose this molecule was incorporated into a cell membrane. Which letter indicates the portion of the molecule that would be exposed to the aqueous environment?

1) To identify which contains more acid vinegar or lemon juice neutralization with sodium hydroxide can be used. Explain how. 2) The long filaments making up the thread of woven synthetic fabrics are likely polyesters. Describe the special characteristic that the alcohol and carboxylic acid must have so that they can react with each other to produce such long filaments.
