why of the dipole, dispersion, and induction can be interaction in the van der waals force? the ability of polarization or molecular polarizabilities is expressed by the simbol alpha.in the molecules with the same shape the increased mass of the molecule would lead to increas in the number of electrons.this causes the nuclei to the influence of the electron could is getting weaker ,so it will easily polarized and london style that occurs will be stronger.London style is more powerfull cause melting and boiling the molecules.Involved in this style requires a great energy to enlarge the non polar intermolecular distances... interaction induced dipole is dependent on two factors, namely: 1. the number of electrons in atoms or molecules the more electrons that possess the greater the molecular interaction 2.molecular shape molecules are elangated or not round more easily be compared with the molecular dipoles are rounded so that their interactions will also be great. compound that have a dipole commonly referred to as polar compound, polar compounds are formed through a polar covalent bond.it shoud be noted that in contrast to ion dipole.owned electric dipole strength is weaker than the ion electric power .we must remember that the ion present ionic compounds where the molecule is divided positive or cation and negative or anion. When the dipole is misguided happens, there will be also the style of london (blue line putis-break). When the dipole is lost, is lost london style. London force strength depends on various factors: A. Complexity of the molecular more complicated molecules (Mr greater), then the force is getting stronger london. 2. Molecular size the larger molecular size, style london also intensified. this is because the large molecules more easily polarized, so that the dipole moment is more apt to occur. Van der Waals forces that occur between the dipole - dipole arranged on a regular basis. Substances that have the style of van der Waals forces in a regular arrangement is usually are solid. The substances which have van der Waals force in disorganized arrangement (random) is usually liquid. Van der Waals forces do not cause spikes in the boiling point. This is due to inter-molecular forces are weak. The dipole-dipole attraction is a bit compared to the dispersion forces, and their effects can only be seen if we compare the two atoms with the same number of electrons of the same size. Appeal that there is electrical in nature. At the symmetric molecules such as hydrogen, does not look distorted to produce the electrically positive and negative parts. Electrons are constantly moving, and at one time the electron is found possible for the end of the molecule. On the other end while the shortage of electrons. At the end of the condition of the right electron will move to the other end. In doing this, the electrons in the electron will be the only one left. Of all the forces that occur in the bonds between molecules called Van der Walls forces no doubt is the weakest force even the most universal. Associated with energy around 0.4 to 40 kJ / mol, this style bias is offset by the stronger covalent forces within the molecule whose energy is about 400 kJ / mol. His role is important only to explain the interaction between neighbor molecules or atomic orbitals fellow saturated. Unlike covalent bonds within the core work in close and connected with the overlap or electron transfer, and result in higher energy, then the Van der Waals bonding can work at a distance which can not cause squeezing or transfer of electrons that are usually associated with energy smaller.
