Answer:
To determine the metal ion responsible for the observed magnetic moment, let's consider the possible options and analyze each one individually.
a) Co2+
If the metal ion is Co2+, it has an electronic configuration of [Ar] 3d7, which means it has three unpaired electrons. According to Hund's rule, these unpaired electrons would result in a magnetic moment. Therefore, option a) cannot be the correct answer.
b) Mn2+
If the metal ion is Mn2+, it has an electronic configuration of [Ar] 3d5, which means it has five unpaired electrons. Similar to the previous case, these unpaired electrons would lead to a non-zero magnetic moment. Thus, option b) is also incorrect.
c) Fe2+
If the metal ion is Fe2+, it has an electronic configuration of [Ar] 3d6, which means it has four unpaired electrons. Again, based on Hund's rule, these unpaired electrons would result in a non-zero magnetic moment. Therefore, option c) is not the correct answer.
d) Fe3+
If the metal ion is Fe3+, it has an electronic configuration of [Ar] 3d5, which means it has five unpaired electrons. However, it is important to note that the Fe3+ ion is highly paramagnetic due to the presence of unpaired electrons. Therefore, the zero magnetic moment observed in the complex of the same metal with the same oxidation state cannot be attributed to Fe3+.
Conclusion:
Based on the analysis above, we can conclude that the metal ion responsible for the observed zero magnetic moment is Fe3+.
