Which among the following statements is incorrect for manganate and permanganate ions?
Options
- ABoth ions are tetrahedral structure.
- BIn both the ions, (p -d ) bonding is observed between oxygen and manganese.
- CBoth ions are paramagnetic.
- DPermanganate is stronger oxidising agent than manganate.
Correct answer
C. Both ions are paramagnetic.
Step-by-step solution
( ) Tetrahedral ( d ( Mn ) _p ( O ) ) is present. ( ) Paramagnetic, due to presence of one unpaired (d )-electron of ( Mn ⁺⁶ (3 d^ ) ) of ( MnO ₄²⁻ ). ( ) Oxidising agent. ( ) Tetrahedral ( d ( Mn ) _p ( O ) ) is present. ( ) Diamagnetic, due to the absence of unpaired (d )-electron in ( Mn ⁺⁷ (3 d^0 ) ) of ( MnO ₄⁻ ). ( ) Stronger oxidising agent.
