Briefly describe a procedure with reagents required to extract eugenol as a single component from the mixture of compounds present in these flower buds. OH LOCH 3 eugenolIn the workup of the grignard reaction of turning bromobenzene to benzoic acid, we start by mixing the grignard with HCl and diethyl ether. We discard the aqueous layer and wash the organic layer with water. Then, the organic layer is extracted with NaOH. Then, the extracts are heated to remove ether. Then, it is precipitated with HCl. Precipitate collected. Let it dry and finally, purified with toluene and hexanes. Please make a flowchart of the process of this workup indicating what products and byproducts are forming. And what compounds are in the aqueous layer and organic layer in the steps.SYNTHESIS OF BENZOIC ACID FROM BASIC HYDROLYSIS OF BENZONITRILE 2.

- Suppose you took your two compounds, dissolved them in tertbutyl methyl ether and then added them to a separatory funnel. Now suppose you add in aqueous sodium bicarbonate and vigorusly shake the contents of the separatory funnel. ethanol will be dissolved in tert butyl methyl ether ether and valeric acid will be dissolved in the aqueous sodium bicarbonate layer. Draw the EXACT chemical structure that will exist in each of the layers after shaking with sodium bicarbonate. (Is it neutral or charged?)A student was performing an acid-base extraction of a mixture of three compounds. The three compounds in the mixture are shown below. The mixture was extracted wilth 6 M HCI three times. The combined extractions were put into a flask marked A, which was treated with 1 M NAOH till it turned basic. This was then evaporated to obtain a crystal, which we label A. The remaining mixture was extracted with 6 M NaOH three times. The combined extractions were put into a flask marked A, which was treated with 1 M HCI till it turned acidic. This was then evaporaled to obtain a crystal, which we label B. The remaining mixture was evaporated to obtain a crystal, which we label C.

Explain why does the colour of the solution change from red to orange to yellow? c) What is the by-product of synthesis of triphenylmethanol?A mixture of the two compounds shown below is dissolved in ether. Using the information given in the experiment, select all the correct statements regarding the extraction and isolation of the two compounds. orto OH ΗΝ X Y A. X is basic because it contains an amine. It can be extracted from the organic layer using hydrochloric acid. B. Y is basic because it contains an amine. It can be extracted from the organic layer using sodium hydroxide. C. Y is acidic because it contains a carboxylic acid. It can be extracted from the ether layer using sodium hydroxide. D. Y is acidic because it contains a carboxylic acid. It can be extracted from the ether layer using hydrochloric acid.The question is: Consider a mixture containing 0.5 benzil and 0.05 biphenyl. Your task is to isolate the benzil in pure form. Would this be best accomplished by recrystallization or extraction? I don’t really know which one would be better cause both can isolate a substance in its pure form. Thanks!
