Why does the neutral compound, triphenylmethane, in this experiment fail to undergo reaction when treated with acid or base (consider the pKa of the neutral compound and acid/base equilibrium)?
Triphenylmethane does not undergo reaction with acid or base
because it is a hydrocarbon with three phenyl group. It is mostly
stable de to presence of phenyl rings in which electrons
delocalized. It does not have proton acidic enough to replace by
base and form salt. Its pKa is around 33 and it remains in
equilibrium with acid or base thus it remains dissolved in organic
layer inspite of how much acid or base added to the system.

Why does triphenylmethane fail to undergo a reaction when treated with an acid or base (mention the pKa of the neutral compound triphenylmethane and acid/base equilibrium)?
Extraction of benzoic acid and 9-fluorenone using diethyl ether. (please do not include ethyl 4- aminobenzoate). I have to create a flow chart to diagram the key steps of the experiment and isolation of products. 0.100g of benzoic acid and 9-fluorenone are dissolved in diethyl ether. The extraction solvent is 5% sodium hydroxide (to extract the acidic component from the organic phase). Saturated sodium chloride is added to the organic layer. drying the organic solution: anhydrous sodium sulfate is added...
Explain the acid/base chemistry that occurred when you separated the organic base and neutral compound. Include chemical equations. The two compounds used were 1,4-dichlorobenzene and ethyl 4-aminobenzoate.

The Separation of Three Organic Compounds by Acid, Base Reactions and Liquid, Liquid Extraction. Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and 9-fluorenone all dissolved in diethyl ether. We separated the basic component by adding 3M HCl, we separated the acidic component by adding 3M NaOH. I don't understand what happens here. To isolate the acidic solution, we added 6 M NaOH and used the vacuum to recover the solid. To isolate the basic solution we added...

Use of Extraction to Isolate a Neutral Compound from a Mixture Containing an Acid or Base Impurity. Part 4D Hi guys I had a question about this lab. I am not sure how to create a flow chart for it as well as what chemical equations it needs. please let me know if you need more information. layer. In the Optional Exercise, the sample contains a neutrum base impurity; however, a detailed procedure is not given. If you are assigned...

Need help on providing reactions that describe the acid-base extraction and neutralization processes used in this experiment. Provide a statement of solubility of each starting material and product. The experiment to be performed this week involves liquid-liquid extraction using a separatory funnel. Read chapter 15 in Zubrick to familiarize yourself with the use of the glassware for extraction and washing. Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substances that have varying solubility...
