Would you expect caffeine to be more soluble in a dichloromethane or in water? Explain the reasoning for your choice of in terms of overall polarity of caffeine.
caffeine will more soluble in dichloro methane than water
dicholomethane is polar organic solvent
water is polar aqueous layer
caffeine is more polar molecule but molecular formula of caffene is C8H10N2O4
though it is polar because of its high molecular formula it will not soluble in water
so it will soluble in dichloro methane
that why while extracting the caffene we will use dichloro methane

2. Which would you expect to be more sol Explain your reasoning. be more soluble in water, strontium thiosultado ntium thiosulfate or calcium thiosulfate? 3. Both chlorine and bromine can act as oxidizing agents. When KCl and Br2 are combined in the presence of methylene chloride, the color of the methylene chloride layer after thorough mixing is the color of bromine. Which is the stronger oxidizing agent, bromine or chlorine? Explain your reasoning.
16. Would you expect 2-octanone to be soluble in water? Would you expect butanal to be soluble in water? Would either of them be more soluble in hexane than in water? Explain.
Is 4-methylbenzyl alcohol more soluble in water or dichloromethane?
Would caffeine be more soluble in water or in HCl? I am confused on how the imfs would effect each reaction.
Let's assume the distribution coefficient of caffeine between dichloromethane and water is 3. You have a 10mL aqueous solution of caffeine that contains 100mg of caffeine dissolved in it. You also have 10mL dichloromethane. If you do just one extraction using 10mL dichloromethane, how much caffeine you can recover from the aqueous solution? 25mg 50mg 75mg 100mg None of the above QUESTION 3 Let's assume the distribution coefficient of caffeine between dichloromethane and water is 3. You have a 10mL...
2. While caffeine is very soluble in water, aspirin is only minimally soluble. a. Clearly explain why you think caffeine is soluble in water. b. In order to dissolve the aspirin, I had to use a sodium hydroxide solution (this is why you had to add HCl to the separatory funnel.) Clearly explain how the use of a sodium hydroxide solution allowed the aspirin to dissolve. Structures/reaction(s) will likely help your answer.
16. Would you expect 2-octanone to be soluble in water? Would you expect butanal to be soluble in water? Would either of them be more soluble in hexane than in water? Explain. 25. Criticize the following techniques: isten (a) Heating a mixture that contains n-hexane using an open flame. (b) For a reaction, heating a mixture that contains a large amount of toluene using hot water bath. (c) Running s reaction with tert-butyl alcohol that is cooled to 0°C in...
Organic chemistry question 4. Benzoic acid is almost 12 times more soluble in dichloromethane than in water at room temperature (the distribution coefficient (K) is 11.7). a) Approximately how many grams of benzoic acid would be recovered in the organic layer if 10.0 g of benzoic acid dissolved in 100 mL of water was extracted with 100 mL of dichloromethane? Show calculations. b) Approximately how many grams of benzoic acid would be recovered if the water layer was extracted a...
Which of the 10 substance would you expect to be soluble in water? Which would you expect to be miscible with water? Which would you expect to be insoluble in water?
