Highest oxidation state of MnMn is exhibited in Mn2O7{Mn}_{2}{O}_{7}. The correct statements about Mn2O7{Mn}_{2}{O}_{7} are

(A) MnMn is tetrahedrally surrounded by oxygen atoms
(B) MnMn is octahedrally surrounded by oxygen atoms
(C) Contains Mn−O−MnMn - O - Mn bridge
(D) Contains Mn−MnMn - Mn bond.

Choose the correct answer from the options given below

Highest oxidation state of Mn is exhibited in Mn _ 2 O _ 7 . The correct statements about Mn _ 2 O _ 7 are (A) Mn is

Options

  1. AA and C only
  2. BA and D only
  3. CB and D only
  4. DB and C only

Correct answer

A. A and C only

Step-by-step solution

Each MnMn is tetrahedrally surrounded by oxygen atoms. In addition, there is a bridging two-coordinated oxygen atom between two tetrahedral units. The bridged Mn−OMn - O has different bond length than the tetrahedrally surrounded Mn−OMn - O bond lengths.

Highest oxidation state of Mn is exhibited in Mn _ 2 O _ 7 . The correct statements about Mn _ 2 O _ 7 are (A) Mn is

So, the correct statement is only A and C.
