An alcohol + a carboxylic acid combine to form an________; the small molecule that is lost in joining the alcohol and carboxylic portions together comes from alcohol -H and carboxylate -OH, to form a molecule of_______.

Create balanced chemical reactions for the following reactions. Organic reactions should be written with the line-angle drawing of each structure. 1.  Reacting salicylic acid with acetic anhydride to form acetylsalicylic acid, with the use of sulfuric acid as a catalyst. 2. Water reacting with acetic anhydride to form acetic acid.

A student found an unknown solution which had the distinct odor of an organic compound. In an attempt to identify the functional group, she performed several of the tests used in Experiment # 6. The observations are tabulated below. a. Primary alcohol b. Carboxylic acid c. Tertiary alcohol d. Secondary alcohol e. Aldehyde f. Ketone Reagent Color of control sample Color after the test Potassium dichromate (K2Cr2O7) Orange Green Potassium permanganate KMnO4) Deep Purple Brown precipitate      Brady's Reagent (dinitrophenylhydrazine)     Red-orange solution Deep red precipitate Legal's reagent (sodium nitropruside) Bright red solution         No change observed; no precipitate either

4. Assume that an esterification reaction is done using 0.10 moles of a carboxylic acid and 1.0 moles of an alcohol. What is the theoretical yield (in moles) for the reaction? (You can write a generic esterification reaction to help answer this question and recognize the limiting reagent.) 5. A student completes the reaction described in question 4 and obtains 5.3 g of the product (the product has a molecular mass of 74.0 g/mol). a) What is the actual yield (the moles of product obtained)? Show your calculation, including units. 5.3 g product X mol products b) Calculate the % yield for the reaction. Show your calculation, including units.

When setting up an organic reaction for the first time, a concentration of reactants in tens to hundreds of micromolar range (mM) is often required. How much solvent (DCM) is required to prepare a solution that has a reactant concentration of 200mM? a) 0.126mL b) 1.26mL c) 12.60mL d) 126mL e) None of the options is correct.

You have a mixture of an aryl halide and a carboxylic acid that you wish to separate(both are solids). Both are soluble in diethyl ether. Explain ALL the steps you would take to obtain the two compounds in pure form from your sample.

Given 8.30 g of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100% yield? Express your answer in grams to three significant figures.
