Question

$SnC{l}_2$ acts as a reducing agent because :

• A. $SnC{l}_2$ can accept electrons readily
• B. $S{n}^{2+}$ is more stable than $S{n}^{4+}$
• C. $S{n}^{4+}$ is more stable than $S{n}^{2+}$
• D. $S{n}^{2+}$ can be easily converted to metallic tin

Answer 1

Answer: (C)

● 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
