Which among the following concepts is NOT introduced by V. B. Theory?
- A Delocalization of electron over the two nuclei.
- B Shielding effect of electrons.
- C Partial ionic character of a covalent bond.
- D Number of lone pair and bonded pair of electrons decide the shape of the molecules.
Answer & Solution
Correct Answer
(B) Shielding effect of electrons.
Step-by-step Solution
Detailed explanation
VBT says that overlapping of half-filled orbitals results in formation of bond. Formation of bond results in delocalization of \(\mathrm{e}^{-}\)and form partial ionic character.
