Hydrogen chloride is a covalent compound with dipole-dipole interactions among the molecules, where as sodium chloride is an ionic compound it contains ion-dipole interactions among the molecules. Dimethyl ether is completely soluble in water but diethyl ehter is soluble isn water to small extent. The reason is because water is more polar than ether and can hydrogen bond with water more freely than with ether since water has both hydrogen bond donor and acceptor atoms. - Most Soluble 2. Tetrahydrofuran (oxacyclopentane) is fully soluble. But now I'm hav en a simulated. So now I alter the p k of this nitrogen.

Re: Glucose and Diethyl ether ohotdang Sun, 10/05/2008 - 13:55 hmm..that's what I assumed at first, but it makes sense that it may have reacted, because no reaction could also mean it is completely soluble, meaning it is just spreaded out well. I just had an extraction lab, and am confused how methyl red is soluble in both water and ether. 1. The melting point of sucrose is 160 °C. My prediction was that methyl red would be only soluble in ether, but it actually dissolved into both layers. Discuss. Ethers are aprotic. L'éther diéthylique, également appelé éther éthylique ou éthoxyéthane ou diéthyl éther ou oxyde de diéthyle ou tout simplement éther (à ne pas confondre avec la famille des éthers dont il fait partie), est un liquide limpide, incolore et très inflammable avec un point d'ébullition bas et une odeur typique. The ether O atom will hydrogen bond to the amine H atoms which gives it even better solvency. C 2 H 5 OC 2 H 5 + 6O 2 → 4CO 2 + 5H 2 O; Halogenation – Ether reacts with halogens like chlorine or bromine forming halo substituted ether undergoes substitution reaction in the absence of sunlight.
