Important Timestamps
0:00:00 - 08:33 = Introduction & Mind map
08:34 -10:35 = Ques. No. 1 Which of the following are the example of double salt?
FeSO4.(NH4)2SO4.6H2O
CuSO4.4NH3.H2O
K2SO4.Al2(SO4)3.24H2O
Fe(CN)2.4 KCN
Choose the correct answer
10:36 - 13:33 = Ques. No. 2 IUPAC name of the compound K3[Co(C2O4)3] is
13:34 - 16:13 = Ques. No. 3 The set which does not have ambidentate ligand(s) is
16:14 - 19:42 = Ques. No. 4 The conductivity of a solution of complex with formula CoCl3(NH3)4 corresponds to 1:1 electrolyte, then the primary valency of central metal ion is ______.
19:43 - 22:14 = Ques. No. 5 Correct formula of the compound which gives a white precipitate with BaCl2 solution, but not with AgNO3 solution, is:
22:15 - 24:10 = Ques. No. 6 Complete removal of both the axial ligands (along the z-axis) from an octahedral complex leads to which of the following splitting patterns ? (relative orbital energies not on scale).
24:11 - 28:51 = Ques. No. 7 Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : [CoCl(NH3)5]2+ absorbs at lower wavelength of light with respect to [Co(NH3)5(H2O)]3+
Reason R : It is because the wavelength of the light absorbed depends on the oxidation state of the metal ion.
In the light of the above statements, choose the correct answer from the options given below :
28:52 - 31:30 = Ques. No. 8 For a d4 metal ion in an octahedral field, the correct electronic configuration is :
31:31 - 35:41 = Ques. No. 9 Which of the following complexes will exhibit maximum attraction to an applied magnetic field ?
35:42 - 40:54 = Ques. No. 10 Match List I with List II
40:55 - 43:44 = Ques. No. 11 The octahedral diamagnetic low spin complex among the following is
43:45 - 45:37 = Ques. No. 12 The complex with highest magnitude of crystal field splitting energy (𝝙0) is
45:38 - 46:53 = Ques. No. 13 Number of bridging CO ligands in [Mn2(CO)10] is ________.
46:54 - 47:35 = Ques. No. 14 The sum of bridging carbonyls in W(CO)6 and Mn2(CO)10 is ________.
47:36 - 49:15 = Ques. No. 15 Given below are two statements: one is labelled as "Assertion A" and the other is labelled as "Reason R"
Assertion A: In the complex Ni(CO)4 and Fe(CO)5, the metals have zero oxidation state.
Reason R: Low oxidation states are found when a complex has ligands capable of π-donor character in addition to the o-bonding.
In the light of the above statements, choose the most appropriate answer from the options given below
49:16 - 50:18 = Ques. No. 16 The number of bridging CO ligand (s) and Co-Co bond(s) in CO2(CO)8, respectively are :
