The correct Answer is:
To solve the question, we need to analyze the assertion (A) and the reason (R) given in the context of Crystal Field Theory (CFT). ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that "According to CFT, complex compounds contain point charges." - In CFT, ligands are considered as point charges that interact with the central metal ion. This is a fundamental concept in CFT, where ligands are treated as charged entities that influence the energy levels of the d-orbitals of the metal ion. 2. **Understanding the Reason (R)**: - The reason states that "The bonding between the central metal ion and ligand is electrostatic." - This statement is also true. The interaction between the metal ion and the ligands is primarily electrostatic in nature, as the positively charged metal ion attracts the negatively charged ligands (or vice versa). 3. **Evaluating the Relationship Between A and R**: - Both the assertion and reason are true statements. However, we need to determine if the reason provided is the correct explanation for the assertion. - The assertion talks about the nature of complex compounds containing point charges, while the reason explains the type of bonding (electrostatic) between the metal ion and ligands. 4. **Conclusion**: - While both statements are true, the reason does not adequately explain why complex compounds contain point charges. The presence of point charges in complex compounds is a characteristic of the ligands and their interaction with the metal ion, but the reason provided focuses solely on the nature of bonding. - Therefore, the conclusion is that both the assertion and reason are true, but the reason is not the correct explanation for the assertion. ### Final Answer: - Both assertion (A) and reason (R) are true, but the reason is not the correct explanation of the assertion. ---

According to C.F.T, attraction between the central metal ion and ligands in a complex is purely electrostatic. The transition metal which forms the central atom cation in the complex is regarded as a positive ion. It is surrounded by negative ligands or neutral molecules which have a lone apir of electrons, if the ligand is a neutral molecule such as NH_(3) , the negative and of the dipole in the molecule is directed towards the metal cation. the electrons on the central metal ion are under repulsive forces from those on the ligands. thus the electrons occupy the d-orbitals remain away from the direction of approach ligands. ltBrgt Q.
