According to VSEPR theory, the repulsions are called:

Correct answer: C. Van der waals repulsion

  • A. Joule repulsion
  • B. Planks repulsion
  • C. Van der waals repulsion
  • D. J.J.Thomson repulsion

Explanation

Option C is correct since Van der Waals forces include attractive forces arising from interactions between the partial electric charges and repulsive forces arising from Pauli's exclusion principle, and the exclusion of electrons in overlapping orbitals. These forces are considered in the VSEPR model.Option A is incorrect since the VSEPR model does not talk about the joule repulsion.Option B is incorrect since the VSEPR model does not talk about the plank repulsion.Option D is incorrect since the VSEPR model does not talk about the J.J Thomson repulsion.

About Chemical Bonding

Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
