Highest oxidation state of Mn is exhibited in Mn2O7. The correct statements about Mn2O7 are (A) Mn is tetrahedrally surrounded by oxygen atoms. (B) Mn is octahedrally surrounded by oxygen atoms. (C) Contains Mn-O-Mn bridge. (D) Contains Mn-Mn bond. Choose the correct answer from the options below :

1. (1) A and C only
2. (2) B and C only
3. (3) A and D only
4. (4) B and D only

Correct answer: (2) B and C only

Solution

Mn2O7 features manganese in a +7 oxidation state, where it is octahedrally coordinated by oxygen atoms, leading to a stable structure. Additionally, the presence of Mn-O-Mn bridges is characteristic of this compound, while tetrahedral coordination and direct Mn-Mn bonds are not present.
