Which of the following oxidation states are the most characteristics for lead and tin, respectively?

Options

A. `+4, +2`
B. `+2, +4`
C. `+4, +4`
D. `+2, +2`

Answer

B

Explanation

`+2, +4`, due to inert pair effect `M^(4+)` ions stability decreases, when we move down the group. In case of `Sn, Sn^(4+)` is more stable than `Sn^(2+)` In case of Pb , `Pb^(2+)` is more stable than `Pb^(4+)`.
