Q1
Easy
Which of the following elements is a transition metal?
A.
Scandium (Sc)
B.
Boron (B)
C.
Calcium (Ca)
D.
Aluminum (Al)
Show Answer & Explanation
Correct Answer: A
Scandium (Sc) is a transition metal as it is located in the d-block of the periodic table, while the other elements listed are either p-block or s-block elements.
Q2
Easy
Which property is characteristic of transition metals?
A.
Forming only ionic compounds
B.
Exhibiting variable oxidation states
C.
Being highly reactive in water
D.
Having low melting points
Show Answer & Explanation
Correct Answer: B
Transition metals are known for exhibiting variable oxidation states due to their ability to lose different numbers of electrons from their d-subshells.
Q3
Easy
What is the electron configuration of the transition metal Iron (Fe)?
A.
[Ar] 4s2 3d6
B.
[Ar] 4s2 3d5
C.
[Ar] 3d7 4s1
D.
[Ar] 4s1 3d7
Show Answer & Explanation
Correct Answer: A
Iron (Fe) has the atomic number 26, and its correct electron configuration is [Ar] 4s2 3d6, indicating it fills the 4s orbital before the 3d orbitals.
Q4
Medium
Which of the following transition metals has the highest melting point?
A.
Tungsten (W)
B.
Iron (Fe)
C.
Nickel (Ni)
D.
Copper (Cu)
Show Answer & Explanation
Correct Answer: A
Tungsten (W) has the highest melting point of all metals, including transition metals, due to its strong metallic bonding and high atomic number, which allows for greater thermal stability.
Q5
Medium
Which of the following statements about transition metals is incorrect?
A.
They form colored compounds.
B.
They exhibit variable oxidation states.
C.
They have completely filled d orbitals.
D.
They are good catalysts.
Show Answer & Explanation
Correct Answer: C
Transition metals typically have partially filled d orbitals, which is a characteristic feature that allows them to exhibit variable oxidation states and form colored complexes. Thus, statement C is incorrect.
Q6
Medium
Which of the following is an example of a paramagnetic transition metal complex?
A.
[Fe(CN)6]3-
B.
[Cu(H2O)6]2+
C.
[MnO4]-
D.
[Ti(H2O)6]3+
Show Answer & Explanation
Correct Answer: B
[Cu(H2O)6]2+ has an unpaired electron in its d orbital, making it paramagnetic. In contrast, the other complexes either have all paired electrons or are not in a state to exhibit paramagnetism.
Q7
Medium
Which of the following transition metals has the highest oxidation state in its compounds?
A.
Manganese
B.
Chromium
C.
Iron
D.
Vanadium
Show Answer & Explanation
Correct Answer: A
Manganese can exhibit a maximum oxidation state of +7 in compounds like KMnO4, making it the highest among the options.
Q8
Hard
Which of the following transition metals exhibits the highest oxidation state in its compounds?
A.
Manganese
B.
Chromium
C.
Ruthenium
D.
Vanadium
Show Answer & Explanation
Correct Answer: A
Manganese can exhibit oxidation states ranging from +2 to +7, with +7 being the highest in compounds like KMnO4.
Q9
Hard
In which of the following complexes does the ligand exert a strong field effect causing a large splitting of d-orbitals?
A.
[Co(H2O)6]2+
B.
[Fe(CN)6]3-
C.
[Cu(NH3)4]2+
D.
[NiCl4]2-
Show Answer & Explanation
Correct Answer: B
Cyanide (CN-) is a strong field ligand and causes significant splitting of d-orbitals in complexes like [Fe(CN)6]3-.
Q10
Hard
Which of the following statements about d-block elements is incorrect?
A.
They often form colored compounds.
B.
They have variable oxidation states.
C.
They only form ionic compounds.
D.
They exhibit catalytic properties.
Show Answer & Explanation
Correct Answer: C
d-block elements can form both ionic and covalent compounds, not exclusively ionic ones.
