Question: why sncl2 is good reducing agent?
Answer: ● SnCl2 acts as reducing agent because - 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.
