  • Question 1
    1 / -0.25

     

    Direction (Q. Nos. 1 - 5) This section contains 5 multiple choice questions. Each question has four choices (a), (b), (c) and (d), out of which ONE or MORE THAN ONE are correct.

    Q. 

    Which of the following complexes have correct name?

     

    Solution

     

     

    Complexes K[Pt(NH3 )Cl5 ] and [Ag(CN)2 ]-  have been given their respective IUPAC names.

     

     

  • Question 2
    1 / -0.25

     

    Which is/are the correctly named?

     

    Solution

     

     

    DMG (bidentate and neutral) is not named correctly, acac, bipy and gly have correct names respectively.

     

     

  • Question 3
    1 / -0.25

     

    The correct name of ligand(s) in IUPAC name is/are

     

    Solution

     

     

    The correct name of ligand in IUPAC name are thiosulphate and cyclopentadienyl [(C5 H5 )- ].

     

     

  • Question 4
    1 / -0.25

     

    The ionisation isomer of [Cr(H2 O)4 Cl(NO2 )Cl] is

     

    Solution

     

     

    Ionization isomers are identical except that a ligand has exchanged places with anion or neutral molecule that was originally outside the coordination complex.
    Thus, in Ionization isomerism the central ion and the other ligands are identical.
    So, according to the definition, Cl-  is replaced by NO2-  in the ionization sphere.
     [Cr(H2 O)4 Cl(NO2 )Cl] ----> [Cr(H2 O)4 Cl(NO2 )]+  + Cl-
    [Cr(H2 O)4 Cl2 ]NO2  ----->[Cr(H2 O)4 Cl2 ]+  + NO2-

     

     

  • Question 5
    1 / -0.25

     

    The ligand(s) which gives chelate complexes is/are

     

    Solution

     

     

    When a di or polydentate ligand used its two or more d onor atoms to bind a single metal ion. It is said to be a chelate ligand. The number of such ligating groups is called the denticity of the ligand. Such complexes are called chelate complex tend to be more stable than similar complexes containing unidentate ligands.

     

     

  • Question 6
    1 / -0.25

     

    Comprehension Type

    Direction (Q. Nos. 6  and 7) This section contains a paragraph, describing theory, experiments, data, etc. Two questions have been related to the paragraph have been given. Each question has only one correct answer among the four given options (a), (b), (c) and (d).

    Passage

    In naming complexes, cation is named first followed by anion. Non-ionic or neutral complexes are given a one word name. The cationic and neutral complex ions are named by writing ‘the number and name of the ligands followed by the name of the central metal ion with its oxidation number in roman numerals within the parenthesis. If the complex is anionic, name of the metals ends with ‘ate ’. When the complex contain two or more metal atoms linked with the help of bridging ligand then each bridging ligand is started with μ.

    Q. 

    Name of [CoBr(NH3 )4 NO2 ] is

     

    Solution

     

     

    The correct name of [CoBr(NH3 )4 NO2 ] is tetramminebromonitrocobalt (II).

     

     

  • Question 7
    1 / -0.25

     

    In naming complexes, cation is named first followed by anion. Non-ionic or neutral complexes are given a one word name. The cationic and neutral complex ions are named by writing ‘the number and name of the ligands followed by the name of the central metal ion with its oxidation number in roman numerals within the parenthesis. If the complex is anionic, name of the metals ends with ‘ate ’. When the complex contain two or more metal atoms linked with the help of bridging ligand then each bridging ligand is started with μ.

    Q. 

    The IUPAC name of [Ni(NH3 )4 ] [NiCI4 ] is

     

    Solution

     

     

    The IUPAC name of [Ni(NH3 )4 ][NiCI4 ] is tetramminenickel (II) tetrachloronickelate (II).

     

     

  • Question 8
    1 / -0.25

     

    Matching List Type

    Direction (Q. Nos. 8  and 9) Choices for the correct combination of elements from Column I and Column II are given as options (a), (b), (c) and (d), out of which one is correct.

    Q. 

    Match the Column I with Column II and mark the correct option from the codes given below.

     

    Solution

     

     

    (i) →(q,t), (ii) →(q ,s), (iii) →(r,t), (iv) →(p ,s)

    The complex PtCl4.5NH3  is designated as [Pt(NH3)5Cl]Cl3  which ionizes to [Pt(NH3)5Cl]3+ + 3Cl- ions. Thus, three moles of AgCl are produced from 3Cl- ions with AgNO3.
    So, PtCl4.5NH3 is Cationic Complex.

     

     

  • Question 9
    1 / -0.25

     

    Match the column I with column II and mark the correct option from the codes given below.

     

    Solution

     

     

     

     

  • Question 10

    Q. Ethylenediamminetetraacetate ion is a polydentate ligand and negatively charged. The magnitude of negative charge is

     

    Solution

     

     

    The correct answer is 4.

     

     

  • Question 11
    1 / -0.25

     

    The oxidation state of the central metai in the complex ion [Fe(EDTA)]- .

     

    Solution

     

     

    In [Fe(EDTA)]- , Let the oxidation state is x then
    x - 4 = - 1
    ⇒x = 4 - 1 = 3

     

     

  • Question 12
    1 / -0.25

     

    The complex potassium dicyanodioxalatonickelate (II) in solution produce....... ions.

     

    Solution

     

     

    The structure of potassium dicyanodio xalatonickelate (II) is
    K4 [Ni(CN)2 (ox)2 ].
    K4 [Ni(CN)2 (ox)2 ] → 4K+  + [Ni(CN)2 (ox)2 ]-  
    This produce 5 ions in solution.

     

     

  • Question 13
    1 / -0.25

     

    Number of EDTA molecules required to form an octahedral complex.

     

    Solution

     

     

    EDTA is hexadentate ligand hence, its coordination number is 6.

     

     

  • Question 14
    1 / -0.25

     

    IUPAC name of [Pt(NH3 )2 Cl(NO2 )] is

     

    Solution

     

     

    Ans: c

    Explanation :Pt(NH3 )2 Cl(NO2 )

    m −2 = 0  

    m = +2  

    (NH3 )2 ⇒Diammine  

    Cl ⇒Chlorido

    NO2 ⇒Nitrito-N. 

    So, IUPAC NAME: diamminechloridonitrito-N-platinum(II)

     

     

  • Question 15
    1 / -0.25

     

    Statement Type

    Direction : This section is based on Statement I and Statement II. Select the correct answer from the codes given below.

    Q. 

    Statement l : IUPAC name of the complex [(NH3 )5 —Cr —OH —Cr (NH3 )5 ]CI5 is pentammine chromium-μ-hydroxopentammine chromium (III) chloride.

    Statement II : IUPAC name of the complex [Ni(dmg)2 ] is bis (dimethylglyoximato) nickel (III).

     

    Solution

     

     

    [Ni(dmg)2 ] : bis (dimethylglyoximato) nickel (II)
