The results for alcohol carbon disulphide are in complete agreement with those mentioned above.doi:10.1038/138882a0ERRERA, J.MOLLET, P.NatureErrera, J., and Mollet, P., Nature , 1936, 138 , 882.Errera, J. and Mollet, P. (1936) Intermolecular forces and O--H absorption bands in ...
and in these cases the sharing of electrons is not equal: the more electronegative nucleus pulls the two electrons closer. In the carbon-oxygen bond of an alcohol, for example, the two electrons in thesigma bond are held more closely to the oxygen than they...

Now using that same logic, both ethanol and water have hydrogen bonds, but ethanol has more electrons so shouldn't it have higher intermolecular forces? I know it doesn't, both because the answer was given as C and because I know that alcohol evaporates quickly and has a strong smell from...
Boiling points are a measure of intermolecular forces. The intermolecular forces increase with increasing polarization (i.e. difference in electronegativity) of bonds. The strength of the four main intermolecular forces (and therefore their impact on bo
How does temperature affect a liquid's intermolecular forces? What is the relationship between the vapor pressure of a liquid and its boiling point? If the intermolecular forces between molecules of a substance were very small, what effect would you expect this ...
forces. In this way, we show that the density scaling law for molecular dynamics near the glass transition provides a sensitive tool to detect thermodynamic regions characterized by intermolecular interactions of different type and complexity for a given material in the wide pressure-volume-temperature...
Molecular clusters were used to model the short-range interactions between the ionic liquid and the primary alcohol, studied using density functional theory calculations, inferring preferred interaction sites, strength of interactions and topological characteristics of intermolecular forces. Dynamic viscosity ...
To find the simple linear function between frequency shift and intermolecular force requires investigation of the perturbance at a distance, which is distinctly larger than the bond length of the OH group. The interaction potentials for five binary fluoro-alcohol/non-polar solvent systems are ...
Which testified that the O atom in the S=O bond has hydrogen bond force with the H atom on the hydroxyl group in the alcohol molecule, and its structure is (CH3)2S=OHO(CH2)3OHS=O(CH3)2; meanwhile, the bond length of the O-H bonds of PDO increases and its strength decreases....
