Assuming that cyclohexanone is the limiting reagent for the synthesis of cyclohexanone oxime and that cyclohexanone oxime is the limiting reagent for the synthesis of caprolactam; what is the overall % yield of caprolactam from cyclohexanone given the percentage yield of each step of the reaction sequence as follows? Give only two significant digits. If the answer is a whole number with two digits, do not include the decimal. 57% 27% cyclohexanone → cyclohexanone oxime → caprolactam Answer:

Both pentane-2,4-dione and ethyl acetoacetate have two carbonyl groups separated by a single carbon atom. Although an equilibrium mixture of pentane-2,4-dione tautomers contains 76% of the enol forms, an equilibrium mixture of ethyl acetoacetate tautomers contains only 8% of the enol forms. Suggest a reason for this difference.

Identify the alcohol molecule in the ester compound butyl methanoate. Select the correct answer below:   butanoic acid   butanol   methanol   methanoic acid

Give the systematic (IUPAC) names for these molecules. Boononon cnolonongron. НаСНз CHОССH2СH2СНCHЗ CH3 phenyl propanoate |4-methyl pentane methanoat Incorrect. You mixed up the acyl and alkoxy portions of the molecule. Name the alkoxy part first, followed by the acyl part.

1.5 mL of 1-pentanol reacts with excess acetic acid to form propyl acetate. Draw the full reaction mechanism and calculate the theoretical yield.

what is  the reaction in order to synthesize 1 - propanol from 1-chloropentane

Use the following atomic weights and quantities to calculate the overall % yield of 4-carboxy-4'-pentyllbiphenyl. Remember that your yield must be based on the stoichiometry (balance the equation!), the limiting reagent, and that grams must be converted to moles. Filling out most of the chart will help. Give only two significant digits in your answer. If after rounding the answer is a whole number, do not include a decimal point.

Answer:

Prostaglandins are a class of cicosanoids, fatty acid derivatives with a variety of extremely potent actions on vertebrate tissues. They are responsible for producing fever and inflammation and its associated pain. Prostaglandins are derived from the 20- carbon fatty acid arachidonic acid in a reaction catalyzed by the enzyme prostaglandin endoperoxide synthase. This enzyme, a cyclooxygenase, uses oxygen to convert arachidonic acid to PGG2, the immediate precursor of many different prostaglandins. Rate of formation of PGG2 with 10 mg/ml ibuprofen (mM/min) Arachidonic acid (mM) Rate of formation of PGG2 (mM/min) 0.190 12.3 0.228 13.9 0.342 17.5 0.570 1.33 22.2 28.8 7.71 8.88 11.9 16.3 24.0 The kinetic data given in the table are for the reaction catalyzed by a mutant of prostaglandin endoperoxide synthase. Focusing here on the first two columns, determine the Vmax and Km of the enzyme. Vmax = Km mM/min mM

Calculate the percent yield and theoretical yield for the following reaction: reduction of 9-Fluorenone to 9-Fluorenol    0.1063 of 9-Fluorenone 1.75 mL of methanol 0.1432 g of sodium borohydride  Final weight of 9-fluorenol = 0.1557 g

Methyl benzoate can be synthesized by a Fisher Esterification reaction, and then this ester can be used as a starting material in the grignard synthesis of triphenyl carbinol. Suppose that in the synthesis of methyl benzoate, a student started with 12 grams of benzoic acid and 29.86 ml of methanol. After finishing the preparation of the ester, 7.63 grams of methylbenzoate was obtained, and the benzoic acid reacted completely. What is the percent yield of the ester? ( density methanol = 0.791 g/ml, methanol = 32.04 g/mol, methyl benzoate = 136.15 g/mol, benzoic acid = 122.12 g/mol )
