The strong intermolecular forces in liquid water are caused by the electrical polarity of the water molecule, which in turn is a consequence of the arrangement of electrons in its oxygen and hydrogen atoms (Fig. 1). The oxygen atom shares a pair of electrons with each of the two hydrogen ...
In this work, the abilities of higher alcohols, long-chain ethers and esters to improve the solubility of methanol in diesel were investigated, and intermolecular forces were also analyzed according to the solubility parameters. Results show that different performance for oxygen-containing chemicals as...
one of them being enthalpy of vaporization. Assuming all other factors to be identical, it is the compound with lower enthalpy of vaporization that will evaporate faster. According to NIST database methanol has enthalpy of vaporization around 38 kJ/mol, butane has enthalpy of vaporization around ...
A model of ideal solution can be developed and then the deviations of real and non-real solutions can also be shown. A solution is said to be ideal if the intermolecular forces between its molecules were just the same as those existing in the separate components of the solution, before ...
Answer to: Generally, the vapor pressure of a liquid is related to: amount of the liquid, atmospheric pressure, temperature, intermolecular forces...
In this computational analysis, the generated 螖 G values are based on the solubilities that were experimentally obtained to simulate the intermolecular forces. The intermolecular interaction data from COSMO-RS provide an insight into the relationship between the intermolecular interactions and its crystal...
When this was done the values of 螖H were found to be 12.3 kJ mol 1 for water + benzene, 14.7 kJ mol 1 for methanol + benzene, 5 kJ mol 1 for ethyl ether + benzene, and 17 kJ mol 1 for acetone + benzene. These values are in addition to energy of interaction due to dispersion...

The rotational spectra of the 1:1 complex formed by acrolein and methanol and its deuterated isotopologues have been analyzed. Two stable conformations in which two hydrogen bonds between the two moieties are formed were detected. The rotational lines show a hyperfine structure due to the methyl ...
