Which among the following concepts is NOT introduced by V. B. Theory?

Options

  1. ADelocalization of electron over the two nuclei.
  2. BShielding effect of electrons.
  3. CPartial ionic character of a covalent bond.
  4. DNumber of lone pair and bonded pair of electrons decide the shape of the molecules.

Correct answer

B. Shielding effect of electrons.

Step-by-step solution

VBT says that overlapping of half-filled orbitals results in formation of bond. Formation of bond results in delocalization of e ⁻ and form partial ionic character.
