The primary and secondary valencies of chromium in the complex ion, dichlorodioxalato chromium (III) [CrCI2(OX)2] 3- are 3 and 6 respectively 

CUET UG Chemistry Question No: 3

The most stable system for a chelate is

Option A : five fused cyclic system

Option B : four fused cyclic system

Option C : three fused cyclic system

Option D : two fused cyclic system

Show/Hide Answer Key

Option A: five fused cyclic system 

Greater is the number of chelate rings, greater is the stability of the chelate. Hence, five fused cyclic system is most stable for a chelate.

[Fe(H2O)5NO]SO4 be x.

[Fe(H2O)5NO]2+

x + 0 + 1 = 2

⇒ x = +1

CUET Entrance Exam Chemistry Question No: 6

The pair of compounds having metals in their highest oxidation states is

Option A : [MnO4], CrO2CI2

Option B : [NiCI4]2- , [CoCI4]

Option C : MnO2 , FeCI3

Option D : [Fe(Cn)6]3- , Co(Cn)6]-3

Show/Hide Answer Key

Option A: [MnO4], CrO2CI2

Only Co+  because of the presence of unpaired electrons in d-orbitals show d-d transition and, hence it is coloured.

CUET Exam Question No: 7

Which among the following will be named as dibromidobis (ethylenediammine) chromium (III) bromide ?

Option A : [Cr](en)3]Br3

Option B : [Cr(en)2Br2]Br

Option C : [Cr(en)Br4]

Option D : [Cr(en)Br2]Br

Show/Hide Answer Key

Option B: [Cr(en)2Br2]Br

Two Br, two (en) and one Cr are parts of the complex.
Charge on the complex is +1.

2 (Br) = -2

2 (en) = 0

1 (Cr) = +3

Thus, complex ion is[Cr(en)2 Br2]+ 

Since, anion is bromide, thus complex dibromido bis (ethylenediamine) chromium (III) bromide is written as  [Cr(en)2Br2]Br

CUET Chemistry Practice Questions No: 8
