diethyl ether being a symmetrical molecule theb dipole moments directed toward the ethrial O atom,cancel out with each other,making the molecule non-polar almost.THF,on the other hand,is not non-polar,obvious from its cyclic structure & hence dissolves in water more than former. Besides,in diethyl ether molecule the -O- group can move freely surrounding across O atom,hence Water molecules face problem during interaction with O atom,which is absent in THF,due to its rigid structure.And thus THF is more soluble in water.

The alcohol group (OH) on ethanol is much more polar then the ether group -O- and thus has much higher solubility.

Is cyclohexanone soluble in water?

Yes but only slightly, but quite often not even one drop will dissolve. It easily dissolves in H2SO4, ethanol, ethyl acetate, diethyl ether, dochloromethane and hexane.


Is n-propanol soluble in ethanol?

Merck Index states its miscible with water, alcohol and ether. Alcohol usually refers to ethanol.


Is Ethoxyethane soluble in alcohol?

That's some odd terminology there, I tell you what. Nearly everyone calls "ethoxyethane" just "ether" or, sometimes, "ethyl ether" or "diethyl ether". "Alcohol" is a class of compounds, but usually means "ethanol". So you've used one excessively pedantic name, and one really ambiguous name. That said, the answer is yes, it is. For that matter, it's soluble in water to some extent.


How do you separate isopropanol from a water-ethanol-isopropanol-solution?

One could try dimethyl- or diethyl-ether but it won't give a 'total' separation, only fractional: more isoprpanol than ethanol is extracted. Ether can be evaporated after this, and-or the whole procedure can be repeated.

How TO remove DMSO?

1. If the compound is soluble in diethyl ether, water wash will completely remove DMSO from the ethereal solution . 2. Otherwise, add little ethanol/ water to the sample, then freeze it at -50 degrees Celsius and lypolise it under high vacuum condition (0.01mm Hg or below).


Do sodium salicylate react with water and diethyl ether?

no, but it dissolves


Why is diethyl ether immiscible in water?

Diethyl ether cannot participate in hydrogen bonding with water. It also has nonpolar side chains which are not attracted to the polar molecule water. Diethyl ether is soluble with water to some extent (6.9g/100mL) but is not miscible.


Why is ethanol soluble in blood?

Blood is mostly water, and ethanol is entirely soluble in water.
