Interpretation:
The procedure for separation of a mixture of benzoic acid,
Concept Introduction:
Benzoic acid is a derivative of benzene; it consists of a
Phenols are also derivatives of benzene. In these compounds, the benzene ring bears a hydroxyl group. Phenols are also slightly soluble in water.
Benzene is a hydrocarbon in which six carbon atoms are joined by a ring with one hydrogen attached to each carbon. These are non-polar compounds, so they are soluble in organic solvents only.

- Synthetize 3-phenyl-2-propenoic acid from benzaldehyde using whatever organic/inorganic reagents are needed. 3-phenyl-2-propenoic = 3-phenylacrylic acidarrow_forwardOxalic acid is found in the leaves of rhubarb, primarilyin the form of the calcium salt. Since high levels of oxalicacid are toxic, only rhubarb stalks are used to make strawberry rhubarb pie.

This alkaloid, lysergic acid, has been of great interest to chemists because of its strange, dramatic action on the human mind. Many derivatives of lysergic acid are known, some with medicinal applications. Perhaps the best known derivative of lysergic acid is the potent hallucinogen lysergic acid diethylamide (LSD): మగవా జి N-H LSD (CH25N;O) Like other alkaloids, LSD is a weak base, with Kp = 7.6 × 107. What is the pH of a 0.94 M solution of LSD? pH =arrow_forwardSuppose you have a mixture of these three compounds. Devise a chemical procedure based on their relative acidity or basicity to separate and isolate each in pure form.arrow_forward
- Although p-hydroxybenzoic acid is less acidic than benzoic acid, o-hydroxybenzoic acid is slightly more acidic than benzoic acid. Explain this result.arrow_forwardAlthough p-hydroxybenzoic acid is less acidic than benzoic acid, ohydroxybenzoic acid is slightly more acidic than benzoic acid. Explainthis result.arrow_forwardEthyl butyrate, CH3CH2CH2CO2CH2CH3CH3CH2CH2CO2CH2CH3, 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+H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l) Part A Given 7.30 gg 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. Part B A chemist ran the reaction and obtained 5.95 gg of ethyl butyrate. What was the percent yield? Express your answer as a percent to three significant figures. Part 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 7.30 gg of…arrow_forward
