(a)
Interpretation:
With help of a chemical test distinguish between cyclohexanone and aniline.
Concept Introduction:
Cyclohexanone and aniline both are insoluble in water. Distinction between them by a test is based on the fact that cyclohexanone is neutral to both acids and bases while aniline is a weak base and reacts with acid.
(b)
Interpretation:
With help of a chemical test distinguish between cyclohexene and cyclohexanone.
Concept Introduction:
Cyclohexene is an
(c)
Interpretation:
With help of a chemical test distinguish between benzaldehyde and cinnamaldehyde.
Concept Introduction:
Benzaldehyde and cinnamaldehyde are distinguished by a test which is based on the fact that cinnamaldehyde has carbon-carbon double bond. Cinnamaldehyde gives unsaturation test while benzaldehyde does not give this test.

- Ethyl 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) Given 8.45 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. A chemist ran the reaction and obtained 5.50 gg of ethyl butyrate. What was the percent yield? Express your answer as a percent to three significant figures. The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0%% yield.
