kaplan says ethers are slightly soluble but the 3rd test on top score said they aren't at all so i got the question wrong. i know they're barely soluble but which would you choose on the actual DAT?

Destroyer says it is soluble since it is polar. Oh well i will go with destroyer.

So if ether was polar and soluble in water wouldn't that make ether extractions in lab impossible?
What is polar about it? It is symmetric.
100% not soluble, as previous poster said, ether extractions.
Not all ethers are symmetric though...so slight polarity does exist.
Ethers can't hydrogen bond because there is no Hydrogen on the Oxygen. Ethers are different from alcohols and carbox acids.i think im still a little confused. i looked at a previous post about this and they said that THF is totally soluble whereas diethyl ether is only slightly soluble so i guess it depends on what the question asks.
also, i was almost positive that ethers don't hydrogen bond but im not sure anymore..do they or does that too depend on what ether it is? thanks!
Ethers can hydrogen bond with water but not with themselves because there is no F-H, N-H, or O-H. So, I think it would be slightly soluble, not sure though.
That is true, but Oxygen on the ether has no hydrogens on it so it can put hydrogens out there for other oxygens to hydrogen bond to.
If you can mix ether with water then you deserve the Nobel.
Haha, yeah now that I think about extraction with the ether and aqueous layer, the fact that ether is insoluble in water makes more sense
im with water88. the lack of a hydrogen on the ether's oxygen doesnt keep it from reacting in hydrogen bonding, it just isnt a two way relationship. ethers are soluble in water but not miscible. the bent shape at the oxygen causes a slightly polar region to build up where the two lone pairs of electrons are and a positive charge where the alkyl groups are. the slightly polar portion allows some level of solvation between water molecules. to my understand, dimethyl ether is miscible in water while other ethers are soluble on some level.
ps - remember that DAT questions arent supposed to be absolute, theyre supposed to say "most of the time" instead of never, etc. So if an answer has never as an option for such a subjective question, its probably wrong.
We need one definite answer people!
First, apparently I'm getting the Nobel Prize because I mixed THF (an ether) and water today........ But the only reason 79 in destroyer says ethers are soluble is because it is a cyclic ether, Tetrahydrofuran and it makes the O bend with the electrons on the outside making it polar and mix with water.
And ethers with small carbon chains like dimethylether are miscible in water but larger carbon chained ethers are completely imiscible in water.
I would look at the question if it were on the DAT and try to figure it out but the answer is going to be that ethers are not soluble in water 90% of the time a question is asked about them.
