Question
1. Diethyl Ether is often used as a solvent in the lab for extraction of organic products. How does its polarity and boiling point favor its use? Many solvents are toxic and/or highly flammable. What precautions have to be taken in their removal? t seleiates better thon a tote f other Sovenis due to ht ori handle with cote and shoull be disposed in the ipriate contoine 2. What solvents were used for extraction in this experiment and what effect will each have on the mixture? CethletherOnofhe sokents used in thi 3. What is the type of flask best utilized for crystallization?Explanation / Answer
1. The Polarity difference between the ether and other aqueous layer should be high because
they should be immiscible. The boiling point of ether should be higher than that of solute
and other aqueous layer. In order to remove the ether after extraction, make sure to not
spill the solvent around the surroundings. You can distill and remove the solvent safely
or safely evaporate the ether solution using reduced pressure.
2. Ether is used to isolate neutral compounds
Carboxylic acids are used to isolate basic compounds
and Phenolic solvents are used to isolate acidic compounds or impurities.
3. These flasks are used avoid the loss of solvent and because of its good shape you
can avoid splashing of solvents while swirling the erlenmeyer flask.
