Question

What is Valence Bond Theory? Explain it's salient features.​

Answer 1

Aɴsᴡᴇʀ:

Valence bond theory states that overlap between two atomic orbitals forms a covalent bond between two atoms.

Salient features of VBT:

1) A central metal ion provide number of vacant s,p & d orbital to ligands to form coordinate bond.

2) Number of vacant orbitals provided by central metal ion will equal to its coordination number.

4) Vacant orbitals undergo hybridisation to form same number of hybrid orbitals.
