Regarding the oxidation states of elements of transition element the incorrect statement is

Options

  1. AM o + 6 is more stable than C r + 6
  2. BW + 6 is more stable than C r + 6
  3. COxoanion of C r + 6 in acidic medium is better oxidizing agent than oxides of Mo and W in +6 oxidation state.
  4. DHigher oxidation states are shown by metals when they are attached to π - acceptor ligands.

Correct answer

D. Higher oxidation states are shown by metals when they are attached to π - acceptor ligands.

Step-by-step solution

Lower oxidation states are shown by metals when they are attached to π - acceptors ligands.
