WebIn an experiment, the solubility of iodine in diethyl ether, n-hexane, Carbon Tetrachloride and toluene was measured. The solubilities were: 337g/kg, 182g/kg,19 g/kg and 13 g/kg. Correlate the solubilities with the solvents Find the value of A+B. Hard Solution Verified by Toppr Correct option is A) WebSolubility and miscibility describe similar phenomena, but they are not the same. Solubility exists on a spectrum. Substances may combine together poorly or very well, and it's possible to describe solutions as "partially soluble" or "mostly soluble." Miscibility, however, is an absolute property that is not expressed in degrees.
Web14 jul. 2024 · Analysis: When considering the acidic cleavage of ethers it is important to realize that S N 2, S N 1, or E1 reactions are possible depending on the conditions. First, … WebAfter 2 h at -75 °C, a solution of iodine (0.26 kg, 1.0 mol) in tetrahydrofuran (0.5 L) was added. The solvents were evaporated and the residue dissolved in diethyl ether (1.0 L). After washing with a 10percent aqueous solution of sodium thiosulfate (2.x.0.1 L), the organic layer was dried over sodium sulfate before being evaporated to dryness.
WebBecause diethyl ether has a dipole moment, polar substances readily dissolve in it. Polar compounds that can serve as hydrogen bond donors dissolve in diethyl ether because they can form hydrogen bonds to the nonbonding electron pairs of the ether oxygen atoms. Ethers are aprotic. http://home.miracosta.edu/dlr/211exp2.htm
