Question

Which is not true according to VBT?

• A. A covalent bond is formed by the overlapping of orbitals with unpaired electrons of opposite spins.
• B. A covalent bond is formed by the overlapping of orbitals with unpaired electrons of same spins.
• C. The greater the extent of overlapping the stronger is the bond.
• D. Overlapping takes place only in the direction of maximum electron density of the orbital.

Answer: (B)

Electrons of the same spin never combine to form a bond. Other facts are true for $VBT$.
