Given below are some of the statements about Mn and Mn ₂ O ₇ . Identify the correct statements. A. Mn forms the oxide Mn ₂ O ₇ , in which Mn is in its highest oxidation state. B. Oxygen stabilizes the Mn in higher oxidation states by forming multiple bonds with Mn. C. Mn ₂ O ₇ is an ionic oxide. D. The structure of Mn ₂ O ₇ consists of one bridged oxygen. Choose the correct answer from the options given below :

Options

  1. AA, B and D Only
  2. BA, B and C Only
  3. CA, B, C and D
  4. DA, C and D Only

Correct answer

A. A, B and D Only

Step-by-step solution

Analyzing each statement: Statement A: In Mn₂O₇, using oxidation state calculation: 2(Mn) + 7(O⁻²) = 0, so Mn oxidation state = +7. This is indeed the highest oxidation state for Mn. TRUE. Statement B: Oxygen stabilizes Mn in +7 oxidation state through multiple bonding (Mn=O double bonds and bridging), reducing electron density effectively. TRUE. Statement C: Mn₂O₇ is primarily a covalent oxide with significant Mn-O covalent bonding character. The oxide is not ionic in nature. FALSE. Statement D: The structure of M
