How does knowing the shape of molecules help you design drugs? Explain how the collision theory relates to the creation of chemical bonds. Explain the way in which atoms are held together in a chemical compound. Describe the bonding in metals and discuss how this explains high el...
Describe the bonding in SO2 and SO3 using the localized electron model (hybrid orbital theory). How would the molecular orbital model describe the [{MathJax fullWidth='false' \pi }] bonding in these ...
Describe the hydrogen bonding between two {eq}H_2O {/eq} molecules.Question:Explain what is meant by hydrogen bonding. Describe the hydrogen bonding between two {eq}H_2O {/eq} molecules.Intermolecular Forces of Attraction:The intermolecular forces of attraction (IMFA)...
Molecular dynamics simulations are performed to test the results obtained from the integral equation. It is observed that important microscopic structural features of the average water density due to hydrogen bonding are reproduced by the integral equation. The integral equation has a simple formal ...
molecules containing hexacoordinate carbon atoms.The analysis uncovers the strong (covalent) interactions of boron atoms as well as the "nondirectional" interaction of central carbon atom with those peripheral atoms.On the other hand,instabilities have been found in the topological networks of (B_6C...
Time-dependent density functional theory study on the electronic excited-state hydrogen bonding dynamics of BHC-nicotinamide in MeOH solution The density functional theory (DFT) and time-dependent density functional theory (TDDFT) methods were performed to investigate the electronic excited-state... J...
Association theories explicitly model interactions such as hydrogen bonding (association) by allowing a molecule to have several electron acceptor and/or donor sites, where sites of different polarity interact. The resulting EoS model the Helmholtz energy, A, by adding an association term to some und...

For association energies of supramolecules or bond energies of covalently bound systems, the energy of the complex is compared to the sum of the optimized energies of the separated porphyrin, fullerene, ferrocene, etc. parts, or in some cases, by calculating a single point energy (non-relaxed)...
Some unusual properties of water are as follows: a. The peculiar properties of water in condensed form are due to the presence of extensive hydrogen bonding between water molecules. b. The abnormally high freezing point, boiling point, heat of vapour
