(a)
Interpretation:
The dominant intermolecular force between a pair of helium atoms and a pair
Concept introduction:
The dominant intermolecular interaction between non-polar molecules is called induced dipole-induced dipole interaction or London dispersion forces. In a molecule, electrons are constantly moving around, and at some instant in time, there may be more electrons on one side of the molecule than there are on the other. The extra electrons on that one side gives rise to instantaneous dipole which can alter the electron distribution on a second molecule by repelling or attracting nearby electrons. This instantaneous dipole is directly proportional to the number of electrons possessed by the molecule that is on the molar mass.
(b)
Interpretation:
Why
Concept introduction:
The boiling point of a compound depends on the strength of the intermolecular forces that exist between molecules. Boiling point is the energy required to break the bonds to change the state of a given molecule. The molecules with more surface area require more energy to break the bonds than the molecules with less surface area.

- -Page: 8 nsition metal ions have high-spin aqua complexes except one: [Co(HO)₁]". What is the d-configuration, oxidation state of the metal in [Co(H:O))"? Name and draw the geometry of [Co(H2O)]? b) Draw energy diagrams showing the splitting of the five d orbitals of Co for the two possible electron configurations of [Co(H2O)]: Knowing that A = 16 750 cm and Пl. = 21 000 cm, calculate the configuration energy (.e., balance or ligand-field stabilization energy and pairing energy) for both low spin and high spin configurations of [Co(H2O)]. Which configuration seems more stable at this point of the analysis? (Note that 349.76 cm = 1 kJ/mol) Exchange energy (IT) was not taken into account in part (d), but it plays a role. Assuming exchange an occur within t29 and within eg (but not between tz, and ea), how many exchanges are possible in the low in configuration vs in the high spin configuration?
