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 :
A. A, B and D Only
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 Mn₂O₇ contains bridged oxygen atoms (Mn-O-Mn linkages) along with terminal Mn=O bonds. TRUE. Statements A, B, and D are correct while C is incorrect. The answer is option (1): A, B and D Only.
