Question

Which of the following element exhibit maximum oxidation state:

• A. \(Cr\)
• B. \(Mn\)
• C. \(Fe\)
• D. \(V\)

Answer 1

The Correct Option is B

To determine which element exhibits the maximum oxidation state among \(Cr\), \(Mn\), \(Fe\), and \(V\), we need to understand the general oxidation states of transition metals. Transition elements typically display a variety of oxidation states because they have partially filled d-orbitals, which allows them to lose different numbers of electrons.

Let's examine each element:

1. Chromium (\(Cr\)): Chromium exhibits a range of oxidation states from +2 to +6. The common ones include +3 and +6.
2. Manganese (\(Mn\)): Manganese exhibits several oxidation states, ranging from +2 to +7. The +7 oxidation state is present in compounds like potassium permanganate (\(KMnO_4\)).
3. Iron (\(Fe\)): Iron typically shows oxidation states of +2 and +3, although it can exhibit other states in some compounds.
4. Vanadium (\(V\)): Vanadium shows oxidation states ranging from +2 to +5. The highest common oxidation state is +5, as in vanadium pentoxide (\(V_2O_5\)).

Among these elements, manganese (\(Mn\)) demonstrates the highest oxidation state of +7. Therefore, the element that exhibits the maximum oxidation state from the given options is:

Mn.

Conclusion: The correct answer is \(Mn\), which can reach an oxidation state of +7, the highest among the given elements.
