Partial charges ordipole moments(resulting from bond polarity) are important in determining molecular polarity. But,allbonds must be considered. If the vectors of partial charge/dipole moment end up canceling out, then the molecule may not be polar. In order to predict dipole moments, you have ...
Determining Polarity The polarity of a bond is determined by a periodic concept called electronegativity. Electronegativity is an expression of an atom's tendency to attract electrons in a chemical bond. In order to determine the polarity of a bond, you must find the difference in the electronega...
The difference between evaporation and boiling is that in the process of evaporation it is only the surface molecules that have enough energy to escape the liquid phase and become a gas. When a liquid boils, on the other hand, the molecules below the surface have enough energy to escape the...
How can a molecular compound have polar bonds but an overall polarity of a non-polar compound, for example BeCl2? Why do polar molecules have a higher boiling point than non-polar molecules? How do you to convert polar to rectangular coordinates? Why is SO_2 non polar whereas SO_3 is po...
How Symmetrical Molecules Can Induce Polarity: On the Paradox of Dilutiondoi:10.1021/cg0342563Thomas WuestClaire GervaisJuerg Hulliger
molecule is planar. The molecule may otherwise form any of several three-dimensional shapes, including tetrahedrons, octahedrons or bipyramids. A molecule's shape affects its material's physical properties, such as its color and phase of matter, and determines how it reacts with other molecules....

If you plot this results, we find out rules. Ra is 5.4±0.5, then it is uncertain dissolve or not. Less than 4.9 that solvents dissolve the polymer. Above 5.9, it will not dissolve. Hansen Sphere To determine if the parameters of two molecules (usually a solvent and a polymer) are wi...
In covalent bonds within molecules, the individual atoms contained share electrons to make the molecule stable. Oftentimes, these bonds result in one of the atoms, which has a stronger attractive force than the others, bringing the electrons toward itsel
Molecules can be represented empirically as well as structurally. Chemists use the VSEPR (Valence Shell Electron Pair Repulsion) model for molecular geometry, or, the determination of a molecule's physical shape. This model takes into account the number of bond sites and number of lone electron ...
