- why is it necessary to cool the acidic exact of aniline in ice before adding solid sodium hydroxide?Discuss in an essay the three proofs for the identification of Unknown in the chemicals Test for Qualitative Tests for carbonyls and Unknown carbonyl leading to the final result of Unknown which is Benzaldehyde. Give greater hierarchy details and specific reasons for Benzaldehyde as Unknown. Explain why benzaldehyde is the result for identification in the chemicals Test for Qualitative Tests for carbonyls and Unknown carbonyl.In extraction process, the solution contains mixture of benzoic acid and sodium chloride and was heated with tap water, chloroform was added in the separatory funnel. Why is it not possible to use alcohol instead of chloroform in this procedure?
- Provide a reasonable reaction procedure to separate each product from the reaction mixture usingthe extraction technique.Which is the more effective extraction technique, single or multiple extractions? Explain.Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. 1-butanol, 2-butanol, and diisopropyl ether all tested negatve (immiscible) in the solubility test with concentrated H2SO4.

Draw the structures of these compounds using ChemDraw and paste here. Which of these is more polar and which of these is less polar? (6) Why is it called "hexanes" and not simply "hexane"?which would be the best extraction procedure to ensure thorough removal of a carboxylic acid byproduct from an organic layer.
- Can you answer and explain this? a. Explain in your own words how the conceptof vapor pressures would differ between simpledistillation and steam distillation and how this appliesto the latter. As we know, steam distillation is used inthe separation of immiscible components, so naturallythere is separation based on affinity towards specificsolvents.
