Suppose in a separatory funnel you had 10mL of water and 10mL of diethyl ether. Briefly describe how you would get diethyl ether into an Erlenmeyer flask with only a minimum amount of water.

Answer #1

Diethyl ether has a density 0.714g/cc and has a solubility of 6.05g/100 mL water.Thus diethyl ether layer will be on the the water layer in the separatory funnel.Thus as we first unlock the stopcock of the funnel it is the water which will be coming out.when almost the water is removed there will be only the diethyl ether with a very low amount of water in the funnel.And we can easily collect that diethyl ether in a Erlenmeyer flusk.

Hope that will help you.plz rate me.

For Organic chemistry lab: Distillation: 1. If the heat source in a distillation is a heating mantle, why should it be set in a holder so it isn’t resting on the bench top? Would a stirring hot plate have to be held above the bench top? Why must the distilling flask be clamped so it cannot fall? Imagine some problem occurring that requires you to immediately remove the heat from the distilling flask. Think about this, then go back to...

Suppose you have discovered a new organic molecule and it is somewhat soluble in water even though it is more soluble in dichloromethane or ether solvents. If you do a single extraction, you get only 60% of your material to transfer from the water to the organic layer. How many washes would it take to extract over 90% of your organic material from the water layer. Explain.

A sample of 4-toluic acid is contaminated with a small amount of sand & toluene. Using active extraction (changing the polarity by addition of certain chemicals) & a gravity filtration to remove a component, describe how you would obtain pure 4-toluic acid in its solid form from this mixture. Note that use of an organic solvent like ether should be used initially, & then any other procedures, including use of a separatory funnel is required.

Ethyl acetate is another common organic solvent used in the type of TLC experiment you performed: it has a higher molecular weight and boiling point than either petroleum ether or diethyl ether, and is more polar than them as well. If ethyl acetate had been used as the mobile phase for a TLC analysis of F and AF, how would their Rf values compare to those found using the 1:1 solvent mixture you used? That is, predict how the behavior...

We are doing a synthesis lab of isopentyl acetate (bannana oil) 1.When heating to form isoamyl acetate, the major reason why we did not use a thermometer to monitor the temperature was? Select one: a. A reflux cannot get hotter than the boiling point of the solvent. b. The water jacket prevents solvent from boiling out. c. Boiling chips prevent bumping. d. Nothing was being distilled out of the flask. e. We did not use a Claisen adpator to prevent...
