Question

Valence bond theory explains the colour of the coordination compounds.

• A. True
• B. False

Answer 1

The correct option is B False

Crystal field theory explains colour and magnetism (as it explains whether a complex has unpaired electron or not).

Valence bond theory doesn't explain the colour of the coordination compounds.

Valence bond and molecular orbital theories are used to explain chemical bonding. Two atoms that have unpaired electrons in their orbitals can overlap to give rise to a chemical bond. A sigma bond (σ ) forms when two atomic orbitals overlap between the nuclei of two atoms (also known as the internuclear axis ).
