Q: Which of the following forces contribute to stability of charge-transfer complexes?
  • A. Resonance forces
  • B. Resonance and London dispersion forces
  • C. Dipole-dipole interactions and London dispersion forces
  • D. Resonance forces and dipole-dipole interactions
Correct Answer: Option D - Charge transfer complexes are the complexes that involve the association of an electron –rich substrate (donor) and an electron – poor substrate (acceptor) in the ground state. They are also known as electron donor-acceptor (EDA) complexes. These complexes get the stability from dipole- dipole interactions and resonance forces.
