Question
Give examples to show that elements of first row of d-block elements differ from second and third row with respect to the stabilisation of higher oxidation states.
✓

Answer

  • Highest oxidation state for the first row element is $+ 7$ as in Mn.
    For the second row, the highest oxidation state is $+ 8$ as in Ru $(RuO_4).$
    For the third row, the highest oxidation state is $+ 8$ as in Os $(OsO_4).$
  • Compounds of Mo$(V)$ of $2nd$ row and $W(VI)$ of $3rd$ row of transitional elements are more stable than $Cr(VI)$ and Mn $(VIII)$ of first row elements.
