Options

  1. A44
  2. B55
  3. C66
  4. D33

Correct answer

C. 66

Step-by-step solution

The manganese heptoxide solubility properties indicate that it is a nonpolar molecular species, which is confirmed by its structure. The molecules consist of a pair of tetrahedra that share a common vertex. The vertices are occupied by oxygen atoms and at the centres of the tetrahedra are the MnMn centres. The connectivity is indicated by the formula O3Mn−O−MnO3{O}_{3}Mn - O - {MnO}_{3}.

The total number of Mn = O bonds in Mn _ 2 O _ 7 is
