Consider the following compounds The correct decreasing order of their reactivity towards hydrolysis is (i) > (ii) > (iii) > (iv) (iv) > (ii) > (i) > (iii) (ii) > (iv) > (i) > (iii) (ii) > (iv) > (iii) > (i)

Multiple Choice Options

  • A V 3+
  • B Ti 3+
  • C Mn 3+
  • D Cr 3+

Step-by-Step Verified Solution

The exactly half-filled and completely filled d-orbital have extra stability and stability is directly proportional to number of unpaired electrons. Mn +3 (22) = 3d 4 4s 0 (4 unpaired electrons) So, Mn 3+ ion is most stable in aqueous solution. Rest all have less number of unpaired electrons.
