d- and f-Block · Manganate and permanganate properties

Consider the following statements about manganate and permanganate ions. Identify the correct statements :
  • (A)The geometry of both manganate and permanganate ions is tetrahedral.
  • (B)The oxidation states of Mn in manganate and permanganate are +7+7 and +6+6, respectively.
  • (C)Oxidation of Mn(II) salt by peroxodisulphate gives manganate ion as the final product.
  • (D)Manganate ion is paramagnetic and permanganate ion is diamagnetic.
  • (E)Acidified permanganate ion reduces oxalate, nitrite and iodide ions.
Choose the correct answer from the options given below:
  1. (1)A, C and D Only
  2. (2)A, B and C Only
  3. (3)A, D and E Only
  4. (4)A and D Only
We corrected a printing error in the original paper

Statement D: source printed “permanganate ions is diamagnetic”.
