Select the correct statement about valence bond approach.a)Each bond i...
The valence bond approach is a model used to describe chemical bonding in molecules. It focuses on the concept of overlapping atomic orbitals to form bonds between atoms.
1. Each bond is formed by maximum overlap for its maximum stability:
In the valence bond approach, a bond is formed when atomic orbitals from different atoms overlap and share electrons. For a bond to be stable, there must be maximum overlap between the participating orbitals. This allows for the efficient sharing of electrons and the formation of a strong bond. Therefore, statement a) is correct.
2. It represents a localized electron model of bonding:
The valence bond approach describes bonding as the overlap of atomic orbitals between two atoms. This localized electron model suggests that electrons involved in bonding are primarily localized between the two bonded atoms, rather than being delocalized throughout the entire molecule. This approach helps explain the directional nature of covalent bonds and the formation of multiple bonds. Therefore, statement b) is correct.
3. Most of the electrons retain the same orbital locations as in separated atoms:
In the valence bond approach, when atomic orbitals overlap to form bonds, the participating electrons retain their original orbital locations. This means that electrons involved in bonding remain close to their respective atoms, resulting in a localized electron distribution. However, it is important to note that in certain cases, such as in resonance structures, electron delocalization may occur. Therefore, statement c) is correct.
Conclusion:
All three statements about the valence bond approach are correct. This approach emphasizes maximum overlap for bond stability, represents a localized electron model of bonding, and suggests that most electrons retain their original orbital locations. The valence bond approach provides a useful framework for understanding and predicting the properties and behavior of molecules.
