    Coordination Compounds NEET Questions

    Que 1. In K4[Fe(CN)6]
    (a) (CN) are linked with primary valency
    (b) (CN) are linked with secondary valency
    (c) K is linked with secondary valency
    (d) K is linked with non-ionic valency
    Ans 1. (b) (CN) are linked with secondary valency
    Explanation: (CN) are linked with secondary valency to the central Fe metal ion. Ligand (CN) is linked to the central atom via a dative bond.

    Que 2. In the coordination compound, K4[Ni(CN)4], the oxidation state of nickel is
    (a) 0                                                                        (b) +1                                     
    (c) +2                                                                      (d) –1
    Ans 2. (a) 0
    Explanation: Let oxidation state of Nickel be x
    (1×4)+x+(4×−1)=0
    ⇒ 4+x−4=0
    ⇒ x=0

    Que 3. The co-ordination number of copper in cuprammonium sulphate is
    (a) 2                                                                                        (b) 6
    (c) 4                                                                                        (d) – 4
    Ans 3. (c) 4

    Que 4. Which of the following acts as a bidentate ligand in complex formation
    (a) Acetate                                                                              (b) Oxalate
    (c) Thiocyanate                                                                      (d) EDTA
    Ans 4. (b) Oxalate (C2O42-)

    Que 5. [EDTA]4– is a:
    (a) monodentate ligand
    (b) bidentate ligand
    (c) quadridentate ligand
    (d) hexadentate ligand
    Ans 5. (d) hexadentate ligand
    Structure:

    Que 6. The co-ordination number of cobalt in the complex [Co(en)2Br2]Cl2 is
    (a) 2                                                                                        (b) 6
    (c) 5                                                                                        (d) 4
    Ans 6. (b) 6
    Explanation:
    In the given complex,
    Co binds with two a bi-dentate ligand en (2 × 2 = 4) and two mono-dentate ligands Cl (2 × 1 = 2).
    Therefore, its co-ordination number is 4 + 2 = 6.
    In the given complex, Co binds with two a bi-dentate ligand en (2 × 2 = 4) and two mono-dentate ligands Cl (2 × 1 = 2).
    Therefore, the co-ordination number is 4 + 2 = 6.

    Que 7. The stabilization of coordination compounds due to chelation is called the chelate effect. Which of the following is the most stable complex species?
    (a) [Fe(CO)5]                                                                       (b) [Fe(CN)6]3–
    (c) [Fe(C2O4)3]3+                                                                (d) [Fe(H2O)6]3+
    Ans 7. (c) [Fe(C2O4)3]3+
    Explanation: [Fe(C2O4)3]3− is a coordination compound that contains oxalate ions as a chelating ligand. Hence, it stabilizes the coordination compound by chelating the Fe3+ ion.

    Que 8. Which of the following ligands forms a chelate
    (a) Acetate                                                                              (b) Oxalate
    (c) Cyanide                                                                             (d) Ammonia
    Ans 8. (b) Oxalate (C2O42-)

    Que 9. Which of the following is a complex metal other than transition metal?
    (a) Haemoglobin                                                                     (b) Chlorophyll
    (c) Ferrocene                                                                           (d) Vitamin B12
    Ans 9. (b) Chlorophyll
    Explanation:

    (b) Secondary valency can be ionized
    (c) Primary and secondary valencies both cannot be ionized
    (d) Only primary valency cannot be ionized
    Ans 10. (a) Primary valency can be ionized

    Que 11. Which of the following is not true for ligand-metal complex
    (a) Larger the ligand, the more stable is the metal-ligand bond
    (b) Highly charged ligand forms strong bond
    (c) Larger the permanent dipole moment of the ligand, the more stable is the bond
    (d) Greater the ionization potential of central metal, the stronger is the bond

    Ans 14. (d) trans-[CoCl2(en)2]+
    Explanation: It is because square planar and octahedral complexes exhibit geometrical isomerism (cis- and trans-forms) and cis- form is only optically active.

    Que 15. Indicate the complexion which shows geometrical isomerism.
    (a) [Cr(H2O)4Cl2]+                                                                  (b) [Pt(NH3)3Cl]
