Q1
Easy
According to Werner's theory, what is the primary coordination number of a complex ion?
A.
2
B.
4
C.
6
D.
8
Show Answer & Explanation
Correct Answer: C
Werner's theory states that central metal atoms in coordination compounds typically possess a coordination number of 6, allowing for a stable octahedral geometry.
Q2
Easy
Which of the following statements best describes Werner's theory?
A.
It explains the magnetic property of compounds
B.
It defines the structural arrangement of ligands
C.
It relates to the color of transition metals
D.
It focuses on the acid-base behavior of solutions
Show Answer & Explanation
Correct Answer: B
Werner's theory emphasizes the structural arrangement of ligands around a central metal ion, outlining how different ligands affect the geometry of coordination compounds.
Q3
Easy
In which type of complex does the central metal ion exhibit a coordination number of 4 according to Werner's theory?
A.
Square planar
B.
Tetrahedral
C.
Octahedral
D.
Linear
Show Answer & Explanation
Correct Answer: A
In coordination complexes, a square planar geometry is typically associated with a coordination number of 4, particularly for d8 metal ions.
Q4
Medium
Which statement best describes Werner's theory regarding coordination compounds?
A.
Coordination compounds consist only of metal ions.
B.
Coordination compounds have a unique spatial arrangement of ligands around a central metal.
C.
Coordination compounds can only form with monodentate ligands.
D.
Coordination compounds are always formed in a 1:1 ratio of metal to ligand.
Show Answer & Explanation
Correct Answer: B
Werner's theory emphasizes that coordination compounds have a distinct spatial arrangement of ligands around a central metal ion, which contributes to their unique properties.
Q5
Medium
According to Werner's theory, which of the following is true about the primary and secondary valencies of a metal?
A.
Primary valency is always satisfied by anions.
B.
Secondary valency can be satisfied by neutral ligands only.
C.
Primary valency corresponds to the oxidation state of the metal.
D.
Secondary valency is determined by the number of ligands attached.
Show Answer & Explanation
Correct Answer: C
In Werner's theory, the primary valency corresponds to the oxidation state of the metal, indicating how many charges the metal can accommodate.
Q6
Medium
Which of the following complexes illustrates a typical example of a coordination compound as per Werner's theory?
A.
[Cu(NH3)4]SO4
B.
NaCl
C.
Fe2O3
D.
MgCl2
Show Answer & Explanation
Correct Answer: A
The complex [Cu(NH3)4]SO4 is a classic example of a coordination compound, conforming to Werner's theory where a metal ion is coordinated to ligands.
Q7
Medium
How does the presence of ligands affect the coordination number of a metal according to Werner's theory?
A.
Increase the coordination number indefinitely.
B.
Determine the coordination number based on their size and charge.
C.
Limit the coordination number to a maximum of 2.
D.
Have no effect on the coordination number.
Show Answer & Explanation
Correct Answer: B
According to Werner's theory, the size and charge of ligands influence the coordination number, determining how many ligands can bond to the central metal ion.
Q8
Hard
According to Werner's theory, which of the following statements about coordination compounds is correct?
A.
Coordination compounds have fixed valency.
B.
The metal ion can form only one type of complex.
C.
Ligands can be neutral, cationic, or anionic.
D.
Coordination number is always equal to oxidation state.
Show Answer & Explanation
Correct Answer: C
Werner's theory states that ligands can be neutral (like water), cationic (like NH4+), or anionic (like Cl-), which allows for the formation of diverse coordination compounds.
Q9
Hard
In a coordination compound, which factor is primarily responsible for determining the geometry of the complex according to Werner's theory?
A.
The nature of the metal ion
B.
The type of ligands present
C.
The oxidation state of the metal
D.
The temperature of the solution
Show Answer & Explanation
Correct Answer: B
The type of ligands present significantly influences the coordination number and geometry of the complex, as different ligands can lead to different spatial arrangements.
Q10
Hard
Which of the following coordination compounds exhibits octahedral geometry according to Werner's theory?
A.
[Co(NH3)6]Cl3
B.
[Cu(H2O)4]SO4
C.
[Ag(NH3)2]Cl
D.
[FeCl4]2-
Show Answer & Explanation
Correct Answer: A
[Co(NH3)6]Cl3 has a cobalt ion surrounded by six ammonia ligands, which forms an octahedral geometry as per Werner's theory.
