Storyboard Text

  • Sure, dipole-dipole result when polar molecules line up their opposite charges. 
  • Madam, can you explain about Dipole-dipole interaction? I already forgot about it
  • It occurs because of the electron distribution, due to the formation of instantaneous dipole moments 
  • How about London Dispersion forces ?
  • Then, let me ask you, what is Hydrogen bonding?
  • it occurs when partially positive charge of Hydrogen is attracted to the negative charge of oxygen, nitrogen or fluorine
  • Molecular dipole occur due to the unequal sharing of electrons in a molecule.  The partially negative charge of one of the polar molecules is attracted to the partially positive charge.
  • London Dispersion forces are the weakest and considered as Van der Waals forces. The more electrons a molecule has, the stronger the London Dispersion forces . Also, the greater the surface area of a molecule, the more temporary dipole attractions are possible.
  • Occurs specifically between a hydrogen atom bonded to either an Oxygen, Nitrogen, Fluorine or Sulfur. Hydrogen bonding is relatively strong force of attraction between molecules and considerable energy is required to break hydrogen bonds.
