Question

Which of the following is mostly used as a reducing agent ?
(1) SnCl2 (2)SnCl4 (3)PbCl2 (4) PbCl4
Kindly provide a suitable reason supporting the answer.​

Answer 1

Answer:

(1) SnC12 I hope that answer be true

Answer 2

Answer:

Option ( 1 ) SnCl₂

Explanation:

Option (1) SnCl₂ is the correct answer .

As Sn belongs to 4th Group it shows variable oxidation states that are +2 and +4

It Electronic Configuration is ns²np²

When we move down the group we find that lower oxidation state is more stable than higher one due to inert pair effect but in case of Sn the inert pair effect is very less thus +4 oxidation state of Sn is more stable than +2 state of Sn

So to gain more stability Sn ( +2 ) loose 2 more electrons to become Sn ( +4 ) which is more stable .
