The correct Answer is:
To solve the question regarding which ligand can show ambidentate property in the complex \([Co(NH_3)_5(NO_2)]Br_2\), we can follow these steps: ### Step 1: Understand the Definition of Ambidentate Ligands Ambidentate ligands are those ligands that can coordinate to a central metal atom through two different atoms, each of which has a lone pair of electrons. This means that the ligand can attach to the metal from two different sites. **Hint:** Look for ligands that have more than one atom capable of donating a lone pair. ### Step 2: Identify the Ligands in the Given Complex In the complex \([Co(NH_3)_5(NO_2)]Br_2\), we have the following ligands: - \(NH_3\) (Ammonia) - \(NO_2^-\) (Nitrite ion) **Hint:** Write down the ligands present in the complex to analyze their properties. ### Step 3: Analyze Each Ligand for Ambidentate Properties 1. **Ammonia (\(NH_3\))**: - It has one nitrogen atom that can donate a lone pair. - Therefore, it can only act as a monodentate ligand. 2. **Nitrite Ion (\(NO_2^-\))**: - The nitrite ion has two potential donor atoms: nitrogen (N) and oxygen (O). - Nitrogen can donate a lone pair, and oxygen can also donate a lone pair. - Thus, \(NO_2^-\) can coordinate through either the nitrogen or the oxygen atom, making it ambidentate. **Hint:** Check the structure of the ligands to see if they have multiple donor atoms. ### Step 4: Conclude Which Ligand is Ambidentate Based on the analysis, the nitrite ion (\(NO_2^-\)) is the only ligand that can show ambidentate properties because it has two donor atoms (N and O). **Final Answer:** The ligand that can show ambidentate property is \(NO_2^-\).

  • Read the passages and answer the questions that follow Co-dominance Mendel's early work with pea plants provided the foundational knowledge for genetics, but Mendel's simple example of two alleles, one dominant and one recessive, for a given gene is a rarity. In fact, dominance and recessiveness are not actually allelic properties. Rather, they are effects that can only be measured in relation to the effects of other alleles at the same locus. Furthermore, dominance may change according to the level of organization of the phenotype. Variations of dominance highlight the complexity of understanding genetic influences on phenotypes. Co-dominance is a type of non-Mendelian inheritance pattern that finds the traits expressed by the alleles to be equal in the phenotype. There is neither a complete dominance nor incomplete dominance of one trait over the other for that given characteristic. In camellia flowers, petal colour is controlled by codominance. When a red flower is crossed with a white flower, all of the offspring are covered in both red and white petals. Which of the following statement is false?

    A
    In the ABO blood type system in humans, blood type AB is an example of codominance
    B
    Both IA and IB are dominant alleles.
    C
    In codominance, blood type AB implies that both dominant alleles are present and expressed together.
    D
    Blood type AA is an example of codominance.

    coordination compounds often show various types of isomerism. The isomerism can be categorized in two main types (a) structural isomerism (b) stereo or space isomerism Structural isomerism arises due to the difference in structures of coordination-sempounds while stereo or space isomerism arises on account of the different positions and arrangements of ligands (atoms or groups) in space around the metal lonStructural isomerism can be classified in following types (i) tonization isomers- which give different ions in solution, e.g. [CoBr(NH_(3))_(5)]]SO_(4) and [Co(SO_(4))_(5)(NH_(3))_(5)]Br Hydrate isomers which differ in H_(2)O as ligand or as hydration, e.g. [Cr(H_(2)O)_(5)]CI_(2)(H_(2)O)]Cl_(2).H_(2)O[CrCl_(2)(H_(2)O)]CI.2H_(2)O (iii) Linkage isomers, which differ in atom linked to 'metal atom, e.g. [CO(NO_(2))(NH_(3))_(5)]^(2+) and CO(ONO)(NH_(3))_(6)]^(2+) Coordination isomers- which involve interchange of ligands, e.g. [Co(NH_(3))_(6)] [Cr(CN)_(6)] and [Cr(NH_(3))_(6)] [Co(CN)_(6)] (v) Coordination position isomerism-which arises in the bridged complexes due to the difference in the attachment of ligands with the metal atoms Q Which of the following coordination compounds, exhibits ionization isomerism
