The incorrect statement is:

Options

  1. AManganate and permanganate ions are tetrahedral
  2. BIn manganate and permanganate ions, the π -bonding takes place by overlap of p-orbitals of oxygen and d-o
  3. CManganate and permanganate ions are paramagnetic
  4. DManganate ion is green in colour and permanganate ion is purple in colour

Correct answer

C. Manganate and permanganate ions are paramagnetic

Step-by-step solution

Manganate MnO 4 2 - Paramagnetic, green in colour, Tetrahedral & contains pπ - dπ bond Permanganate MnO 4 Θ Diamagnetic, purple in colour, Tetrahedral & contains pπ - dπ bond
