Question

Which of the following statements is correct regarding the Valence Bond theory?

• A. Covalent bonds are formed when two valence orbitals (half-filled) belonging to two different atoms overlap with each other
• B. The unpaired electrons in the valence shell participate in the formation of a chemical bond
• C. Formation of a covalent bond leads to the stability of molecule
• D. All of the above.

Answer 1

The correct option is D All of the above.

Valence Bond Theory illustrates that two half-filled valence orbitals of two different atoms overlap and produce a chemical bond between two atoms. The unpaired electrons are shared and a covalent bond is formed.
Formation of a covalent bond leads to the stability of molecule.
