Interpretation:
The structure of the acid and the alcohol from which the pineapple flavoring ester could be synthesized is to be stated.
Concept introduction:
The reaction between acid and alcohol gives an ester as a major product. The carboxylic acid loses its

- 1. Give at least four medicinal uses of salicylic acid. 2. What are the roles sulfuric acid in the synthesis of salicylic acid? 3. What are the effects of the carboxyl group to the activity of salicylic acid?arrow_forwardThe hydrolysis of an amide in acidic conditions forms A. a carboxylate salt and an alcohol B. a carboxylate salt and an amine C. an alcohol and an amine salt (an ammonium ion) D. a carboxylic acid and an amine salt (an ammonium ion)arrow_forwardEster 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…arrow_forward

Why was aspirin modified and patented into its ester acetylsalicylic acid form that we know today?arrow_forward1) 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.arrow_forwardPhysical properties of carboxylic acids, and its all derivativesarrow_forward

Acetic acid is present in sour milk C. Citric acid is a tricarboxylic acid D. Formic acid is present in insect bites 2. The greater acidity of carboxylic acids compared to alcohols arises primarily from: A. the electron-withdrawing effect of the carboxyl oxygen B. the electron-donating effect of the hydroxyl group C. the acidity of a hydrogens of carboxylic acids D. the resonance stability associated with the carboxylate ion 3. Amides are commonly prepared by reacting acyl halides, esters, or anhydrides with? A. Tertiary amines B. Ammonium hydroxide Please answer all thank you C. Ammonium chloride D. Ammoniaarrow_forward
