What is The colour of (TiF6)3-is
Answers
Answer:
colour of Ti +3 is violet
colourless
Explanation:-
Crystal field theory is a model of the bonding in complexes. Let's consider the octahedral complex [TiF6]3–. According to crystal field theory,
Bonding in this complex is ionic and involves the electrostatic attraction between the Ti3+ ion and the F– ligands.
The F– ligands repel one another and adopt the octahedral geometry.
The metal–ligand attractions are greater than the ligand–ligand repulsions, and the complex is stable.
Ion–dipole attractions are responsible for the stability of complexes formed with neutral dipolar ligands.
The crystal field theory enables us to explore the origin of color in complexes. Incoming ligands interact with the metal ion's d orbitals. The figure below illustrates the orientation of d orbitals with respect to an octahedral array of charged ligands.
