What is the geometry of permanganate ion?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Tetrahedral
In the permanganate ion, \( \ce{MnO4^{-}} \), manganese is in the +7 oxidation state and is surrounded by four oxygen atoms arranged tetrahedrally. The Mn–O bonds also have π character, formed by overlap of filled p orbitals of oxygen with empty d orbitals of manganese.
So the geometry of the permanganate ion is tetrahedral.
