Question

The metal that shows highest and maximum number of oxidation states is:

• A. Fe
• B. Mn
• C. Ti
• D. Co

Hint:

Transition metals have multiple oxidation states due to variable electron loss from \( s \) and \( d \)-orbitals.

Answer 1

The Correct Option is B

Step 1: Understanding Transition Metal Oxidation States
Transition metals display diverse oxidation states because their \( d \)-orbitals are accessible for chemical bonding.
Step 2: Oxidation States of Specified Metals
Mn (Manganese) exhibits oxidation states from \( +2 \) to \( +7 \), the highest among these metals.
Fe (Iron) exhibits \( +2, +3, +6 \).
Co (Cobalt) exhibits \( +2, +3, +4 \).
Ti (Titanium) exhibits \( +2, +3, +4 \).
Conclusion: Mn demonstrates the greatest variety of oxidation states.
