QNEET-2024-Ch-5: NEET 2024 Chemistry - Class 12 NEET-2024-Ch-5 Solution: Given below are two statements: Statement I:…

To determine the correctness of these statements and choose the correct option, we need to understand the concepts of homoleptic and heteroleptic complexes: Homoleptic Complex : A complex in which a central atom is surrounded by only one kind of donor atom or identical ligands is known as a homoleptic complex. An example would be [ Co ( NH 3 ) 6 ] 3 + , where all the ligands are ammonia ( NH 3 ). Heteroleptic Complex : A complex in which a central atom is surrounded by more than one kind of donor atom or different ligands is known as a heteroleptic complex, such as [ Co ( NH 3 ) 4 Cl 2 ] + which contains two different types of ligands, ammonia ( NH 3 ) and chloride ( Cl _ ). Statement I: [ Co ( NH 3 ) 6 ] 3 + is a homoleptic complex whereas [ Co ( NH 3 ) 4 Cl 2 ] + is a heteroleptic complex. This statement is accurate because [ Co ( NH 3 ) 6 ] 3 + indeed is a homoleptic complex as it consists only of ammonia ligands. Conversely, [ Co ( NH 3 ) 4 Cl 2 ] + is a heteroleptic complex, containing both ammonia and chloride ligands. Statement II: Complex [ Co ( NH 3 ) 6 ] 3 + has only one kind of ligands but [ Co ( NH 3 ) 4 Cl 2 ] + has more than one kind of ligands. This statement is also true. As explained, in [ Co ( NH 3 ) 6 ] 3 + , there is only one type of ligand (ammonia), and in [ Co ( NH 3 ) 4 Cl 2 ] + , there are two different types of ligands (ammonia and chloride), which is consistent with the definition provided. Conclusion: Both Statement I and Statement II are true. Therefore, the correct choice is: Option A: Both Statement I and Statement II are true
