WebJan 4, 2024 · Ethanol is completely soluble in water, but when a liter of ethanol is added to a liter of water at 20°, only 1.93 liters of the mixture is produced. Since the hydrocarbonlike ethyl groups of the alcohol cannot hydrogen bond, they slip into holes in the water structure and do not increase the total volume quite proportionally. WebApr 7, 2024 · Thus, ethyl alcohol is more soluble in water than dimethyl ether because alcohol contains hydrogen bonding. Thus, the correct option is (B) alcohol contains hydrogen bonding. Note: In ether, oxygen atoms are not forming hydrogen bonds. This makes ether soluble in water. Hydrogen bonding is possible in ethyl alcohol.

WebAug 29, 2004 · The folded state is stabilized mainly by the burial and tight packing of over 80% of the peptide groups and non-polar side chains. If life as we know it is to exist in a solvent other than water, the folded state must be stable and soluble in the new solvent. Our analysis suggests that proteins will be unstable in most polar solvents such as ... WebUm, and so that's why bees wax is soluble and chloroform, um, slightly soluble and ethanol, because ethanol is still pretty polar and then water is very polar. And so, uh, since like dissolves like very polar and somewhat polar solvents, water and ethanol are not going to be able to resolve a very non polar molecule like bees wax.
