Nevertheless, it is common practice to designate these bonds asionic bonds. This practice is reasonable because of the formation of separate, fully-charged ions when compounds involving these extremely polar bonds are placed in water. (See ion-dipole IMFs below.) Examples: Na-Cl, K-F然而,通常...

simple rule is “like dissolves like” and it is based on the polarity of the systems i.e. polar molecules dissolve in polar solvents (e.g. water, alcohols) and non-polar molecules in non-polar solvents (e.g. the hydrocarbon hexane). This is why ionic compounds like table salt (sodium...
Ionic liquids (ILs) have emerged as suitable options for gas storage applications over the past decade. Consequently, accurate prediction of gas solubility in ILs is crucial for their application in the industry. In this study, four intelligent techniques including Extreme Learning Machine (ELM), De...
(the less non- polar substituents the molecule has), the more soluble the molecule. Also, the more polar groups the molecule contains, the more soluble it is. For ionic compounds, the less effective the ionic charge, the greater the solubility; charge is less effective when the ions are ...
The model was derived from a set of 2874 measured solubilities using linear regression against nine molecular properties. The most significant parameter was calculated logP(), followed by molecular weight, proportion of heavy atoms in aromatic systems, and number of rotatable bonds. The model ...
Non-polar side chain amino acids contribute to lipophilicity of peptide, as they do not bind or give off protons, or participate in hydrogen or ionic bonds, and associate with cellular membranes. Polar side chain amino acids (uncharged) have zero net charge at neutral pH. Serine, threonine,...
Which of the following statements is true? A. In general, the solubility of a gas in water decreases with increasing temperature. B. The solubility of a gas in water usually increases with decreasing pressure. C. The solubility of an ionic solid i...
ionic liquid, particularly [EMIm][OAc], water, and DMSO, as well as the hydrogen bonds between them. Inaccurate modeling of these directed interactions may lead to an imprecise description of the delicate hydrogen bond network. Therefore, we have developed optimized force field parameters for DMSO...
