Question

Which of the following statements is INCORRECT according to the valence bond theory?

Options

• The number of unpaired electrons present in the atoms is equal to the number of covalent bonds formed.

• Only the valence shell electrons having nearly the same energy are involved in the covalent bond formation.

• Geometry of the molecule will be decided by the directional nature of the overlapping orbitals.

• Strength of the covalent bond is inversely related to the extent of overlapping of atomic orbitals.

Answer 1

Strength of the covalent bond is inversely related to the extent of overlapping of atomic orbitals.

Explanation:

According to VBT, the strength of a covalent bond is proportional to the extent of atomic orbital overlap.
