Solution

The correct option is C Sn4+ is more stable than Sn2+

● SnCl2 acts as reducing agent because -

  • -Sn has electronic configuration [Kr] 4d10 5s2 5p2.
  • -Sn doesn't exhibit inert pair effect & thus higher oxidation state is more stable.
  • -Sn4+ is more stable than Sn2+.
  • -SnCl2 readily reacts with other compounds & get converted to stable SnCl4.
  • -During the reaction, SnCl2 gets oxidised while other compound is reduced.
  • -Thus, SnCl2 is a good reducing agent.
  • So option (c) is correct
