CFT gives total emphasis on ?
Answers
Explanation:
CFT successfully accounts for some magnetic properties, colors, and hydration energies of transition metal complexes, but it does not attempt to describe bonding.
Answer:
Concept :
The propensity of transition metals to form complexes is one of their key characteristics. A complex can be thought of as having several ligands encircling a core metal atom or ion. Crystal field theory governs how these ligands interact with the main metal atom or ion. The geometrical or spatial disposition of d orbitals must be understood in order to adequately comprehend the crystal field interactions in transition metal complexes. A free gaseous metal ion has fivefold degenerate d-orbitals. The d-orbitals will remain degenerate but there will be some changes in the energy of the free ion if a spherically symmetric field of negative ligand filled charge is applied to a central metal ion.

Answer:
According to crystal field theory, the orientation of a transition metal cation's d orbitals inside of a coordinating set of anions, commonly known as ligands, results in a net change in crystal energy. The propensity of transition metals to form complexes is one of their key characteristics. A complex can be thought of as having several ligands encircling a core metal atom or ion. Crystal field theory governs how these ligands interact with the main metal atom or ion.
The interaction between a metal ion and ligand is viewed by the 1929-founded crystal field theory as essentially an electrostatic phenomena, with the ligands being viewed as point charges close to the atomic orbitals of the central atom. Through the use of molecular orbital theory, crystal field theory was developed and expanded to take into consideration the partially covalent nature of bonding between the ligand and metal atom. Ligand field theory is another name for crystal field theory.
