Q. The most commonly used reducing agent is
The p-Block Elements
A
$AlCl_3 $
28%
B
$PbCl_2 $
9%
C
$SnCl_4 $
17%
D
$SnCl_2 $
46%
Solution:
$+4$ oxidation state of $Sn$ is more stable than $+2$ oxidation state.
Therefore, $Sn ^{2+}$ can be easily oxidised to $Sn ^{4+}$ and hence $SnCl _{2}$ acts a reducing agent.
$SnCl _{2}+2 Cl \longrightarrow SnCl _{4}+2 e ^{-}$
