Chapter 19.5, Problem 13CC

Name and draw the structure of the major product in the following reactions of cyclohexanone: A) Reduction with NaBH4 in ethanol, followed by H+ B) Reaction with excess ethanol in the presence of H+

Ethyl butyrate, CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple. Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring.It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l). The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 8.50 gof butanoic acid and excess ethanol? Express your answer in grams to three significant figures.

What was the percent yield? c) The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0% yield. How many grams would be produced from 7.70 g of butanoic acid and excess ethanol?

Show how you would synthesize each compound, starting with an ester containing nomore than eight carbon atoms. Any other necessary reagents may be used.(a) Ph3C¬OH (b) (PhCH2)2CHOH

Phenylethanol can be oxidised to phenylethanal or phenylethanoic acid, depending on the reagents used (both the alcohol and the aldehyde are of interest for their antimicrobial properties, while the acid is used to treat type II hyperammonemia): A (a) (b) (c) CoH,CH,CHO phenylethanal B C6H5CH₂CH₂OHC₂H₂CH₂CO₂H phenylethanol Suggest reagents (shown as A and B in the scheme above) that could be used to carry out the oxidation of the alcohol to the aldehyde and the acid, respectively. C6H5CH₂- Suggest two other syntheses of phenylethanoic acid, in each case indicating the starting materials and other reagents required, but not giving details of mechanism. One of your proposed syntheses must start with a compound which only contains seven carbon atoms (the acid product contains eight carbon atoms). phenylethanoic acid Phenylethanal can be converted to a hydrate in the presence of aqueous acid, though the position of equilibrium is very far to the left: H H+/H₂O OH C6H5CH₂-C-H OH Explain why…

A dialkyl-substituted benzene, C14H22, is treated with basic potassium permanganate, followed by acid workup. The same dialkyl-substituted benzene was recovered afterward from the reaction mixture. Draw the structure of the compound.

Describe how 3-methyl-1-phenyl-3-pentanol can be prepared from benzene. You can use any inorganic reagents and solvents, and any organic reagents provided they contain no more than two carbons.

When trans-2-chloro-1-cyclohexanol is treated with a base, cyclohexene oxide is the product. However, when cis-2-chloro-1-cyclohexanol is treated with a base, the product is cyclohexanone –
