Chapter 24: Problem 3

Discuss the salient features of valence bond theory. What are all its applications?

Short Answer

Expert verified

Valence Bond Theory explains chemical bonding by suggesting bonds occur when atomic orbitals overlap and electrons within these overlapped orbitals form bonds. The electrons should have opposite spins and the overlap can occur in different types of orbitals. The theory is crucial in explaining the formation of covalent bonds, predicting bond length and energy, explaining hybridization and resonance, the formation of sigma and pi bonds, and understanding various aspects of molecular structures and their properties.

Step by step solution

Discuss the Salient Features of the Valence Bond Theory

The key features of VBT are: 1. It proposes that bonds are formed when atomic orbitals on different atoms overlap and the electrons within the overlapping orbitals form bonds. 2. This theory suggests that the spins of the bonding electrons must be paired. In other words, the two bonding electrons in a bond must have opposite spins. 3. The overlaps can occur in pairs of s orbitals, pairs of p orbitals, or between an s and a p orbital. 4. The atom's orbitals that are closer in energy tend to hybridize, giving rise to the formation of hybrid orbitals. 5. This theory can account for the geometrical shape of molecules.

Explain the Applications of the Valence Bond Theory

Valence Bond Theory has several important applications, including: 1. It offers an explanation for the formation of covalent bonds in atoms. 2. It can predict the bond length and bond energy for simple molecules. 3. It explains the concept of hybridization, resonance, and the shape of the molecules. 4. It can account for the formation of sigma and pi bonds. 5. Overall, it helps in understanding various aspects of molecular structures and their properties.
